Reflection and Refraction of light - Introduction for kids
 
06:18
The best and the biggest channel for science videos for kids. Light can bounce off when it hits objects and it can bend also while passing through from one medium to another. When we look in a mirror, we can see ourselves because the light shining on our body is reflected from the mirror back to our eyes. If you put a pencil in a glass of water,you will find that the pencil appears bent from the point it enters the water. This experiment proves the property of reflection of light. In this elementary science educational video kindergarten kids,preschoolers,and primary school children can learn science of light and more.

Light Absorption, Reflection, and Transmission
 
04:55
118 - Light Absorption, Reflection, and Transmission In this video Paul Andersen explains how light can be absorbed, reflected, or transmitted as it moves from one medium to another. The reflection of different wavelengths creates the perceived color of an object. Absorbed light is converted to energy and transmitted light moves through the material.

Laws of Reflection | It's AumSum Time
 
05:21
Our topic for today is Laws of Reflection. Consider this ray of light which strikes a mirror. This ray of light is called the incident ray. The point at which the incident ray strikes the mirror is called point of incidence. Draw a line perpendicular to the mirror through the point of incidence. This line is called Normal. The angle which the incident ray makes with the normal is called the angle of incidence. When this ray strikes the mirror, it will bounce off the mirror. This ray which bounces off is called the reflected ray. The angle which the reflected ray makes with the normal is called angle of reflection. Now, let us study the 2 laws of reflection. The angle of incidence is always equal to the angle of reflection. If the angle of incidence is 30 degrees, then the angle of reflection will also be 30 degrees. Remember that, these angles are always measured from the normal, not from the mirror. The incident ray, the normal at the point of incidence and the reflected ray, all lie in the same plane.

03:00
TRANSCRIPT: EXPLORE ACTIVITY -- 5.6 C: Light (Grade Level 5) [Overview Statement] In this activity, students use the materials to investigate what happens when light is reflected and when light is refracted. [Materials] Prepare the following items in advance (for each group in your class): 3 mirrors, a flashlight, tape, a lens with a 25-millimeter focal length, a lens with a 200-millimeter focal length, two pieces of cardstock, a small clear bowl, a penny, a ruler, scissors, crayons or map pencils, and index cards. [Part I Title:] Reflection Let’s first explore reflection. [Or just…] Reflection. [Section 1:] To see the effect of two mirrors taped together, place them on the journal template and align the angle to position 1 on each side. Ask your class how many stars they see and have them record this observation. Repeat the exercise with positions 2, 3 and 4. [Section 2:] Now create a kaleidoscope using three mirrors. Tape each side together to form a triangle. Place the mirrors over a colorful design, or have students draw and color their own. Rotate the kaleidoscope and record how the image appears to distort. FADE TO BLACK.

Reflection of Sound - Class 9 Tutorial
 
04:58
Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves. When sound travels in a given medium, it strikes the surface of another medium and bounces back in some other direction, this phenomenon is called the reflection of sound. The waves are called the incident and reflected sound waves. First Law of Reflection: The incident wave, the reflected wave, and the normal at the point of incidence lie on the same plane. Second Law of Reflection: The angle of incidence is equal to the angle of reflection.

Our topic for today is Introduction to Light. Light is a form of energy that enables us to see all the things around us. The main source of light on the earth is the sun. Plants are able to prepare their own food using sunlight. Some other objects also give out light. They are known as luminous objects. For example, bulbs, lamps, candles, etc. are luminous objects. While there are some objects that do not give out light. They are known as non luminous objects. For example table, cloth, bag, utensils, etc. are non luminous objects. Non luminous objects are generally of two types, transparent objects and opaque objects. Transparent objects are those that allow light to pass through them, like glass, water etc. While, Opaque objects are those that do not allow light to pass through them, like wood, stone etc.

Reflection of lightDefinition: When light ray strikes the boundary of two media such as air and glass, a part of light is turned back into the same medium. This is called reflection of light.A highly polished surface, such as a mirror, reflects most of the light falling on it.Laws of reflection: 1.The angle of incidence is equal to the angle of reflection, and 2.The incident ray, the normal to the mirror at the point of incidence and the reflected ray, all lie in the same plane.These laws are applicable to all types of reflecting surfaces including spherical surfaces.Types of reflection: The types of reflection are regular reflection and irregular or diffused reflection.Regularreflection.It occurs when a beam of light falls on a smooth and polished surface such as a plane mirror. Irregular reflection. It occurs when a beam of light falls on a rough surface such as wall of a room.Incident ray:Light ray striking a reflecting surfacePoints of incidence:The point at which the incident ray strikes the reflecting surface.Reflectedray:The light ray obtained after reflection from the surface, in the same medium in which the.incident ray is travelling. Normal:The perpendicular drawn to the surface at the point of incidence. Angle of incidence:The angle which the incident ray makes with the normal at the point of incidence. It is denoted by the letter i.Angle of reflection:The angle which the reflected ray makes with the normal at the point of incidence.It is denoted by the letter r.Plane of incidence:The plane containing the incident ray and the normal.

ILLUMINATION ENGINEERING - PART - 02 -  IMPORTANT DEFINITIONS AND FACTORS
 
17:21
ILLUMINATION ENGINEERING – PART – 02 IMPORTANT DEFINITIONS AND FACTORS 12. LUMINANCE – When brightness is considered in terms of measureable quantity, the term luminance is employed. Bigger unit of luminance is stilb which is defined as candelas per square cm. 13. UNIFORM DIFFUSE SOURCE – A uniform diffuse source is one in which the intensity per unit projected area is the same from all directions of view. 14. ILLUMINATION LEVEL – The term means the amount of illumination (or light) required to do a job satisfactorily; more light is needed in hospital operation theater compared to normal office work. 15. REFLECTION OF LIGHT - When light falls on a polished surface, it may be partly reflected. The phenomenon is known as reflection of light. The ray of light falling on the surface is known as INCIDENT RAY, and the ray of light, going away after striking the surface is known as REFLECTED RAY. 16. SPECULAR REFLECTION – When the surface is smooth and perfectly reflecting, all the light is reflected i.e. the angle of incidence is equal to the angle of reflection. In this case, a sharp image of the source also appears in the surface. This is known as SPECULAR REFLECTION. This produces brightness of the surface and is responsible for direct glare in eyes. 17. DIFFUSE REFLECTION – When light is incident on coarse (rough) surface then it is scattered or diffused in all directions and hence no image of the source is formed. Such a reflection is known as DIFFUSE REFLECTION. 18. GLARE - It may be defined as the brightness within the field of vision of such a character as the cause annoyance, disc comfort, interference with vision or eye fatigue. 19. LAMP EFFICIENCY – Lamp efficiency is defined as the ratio of the luminous flux to the power input. It is expressed in lumens per watt. 20. SPECIFIC CONSUMPTION - Specific consumption is defined as the ratio of the power input to the average candle power. It is expressed in watts per candela. 21. MEAN HORIZONTAL CANDLE POWER (M.H.C.P) – It is defined as the mean of candle powers in all directions in the horizontal plane containing the source of light. 22. MEAN SPHERICAL CANDLE POWER (M.S.C.P) – It is defined as the mean of candle powers in all directions and in all planes from the source of light. MSCP = Total flux in lumens/4 ∏ 23. MEAN HEMI-SPHERICAL CANDLE POWER (MHSCP) – It is defined as the mean of candle powers in all directions above or below the horizontal plane passing through the source of light. 24. STERADIAN – It is the unit of solid angle and is defined as the solid angle that subtends a surface on the sphere equivalent to the square of the radius. 25. COLOUR – The sensation of colour is due to the difference in wavelengths of the light radiation. IMPORTANT FACTORS AND RATIO 01. RELATIVE LUMINOSITY FACTOR – The sensitivity of the eye to yellowish-green radiation is taken as unity or 100% and the sensitivity to other wave lengths is expressed at a fraction or percentage of it. The relative sensitivity at a wave length λ is written kλ and is known as relative sensitivity. 02. REDUCTION FACTOR (RF) - This is the ratio of MSCP to MHSCP. i.e., MSCP/MHSCP 03. REFLECTION FACTOR (RF) – This is the ratio of the reflected light to the total incident light on a surface. Reduction Factor = Amount of reflected light / Total incident light. 04. UTILISATION FACTOR (UF) – The ratio of total lumens reaching the working plane to total lumens given out by the lamp. 05. WASTE LIGHT FACTOR – It is also called as coefficient of utilization. It is the ratio of the light incident on the working surface to the total light emitted by the source. It theoretical value of lumen required by 1.2 for rectangular areas and 1.5 for irregular areas and objects such as statures, monuments etc. 06. MAINTENANCE FACTOR (MF) – It is the ratio of illumination under normal working conditions to the illumination when the things are perfectly clean. 07. DEPRECIATION FACTOR (DF) – This is the reverse of maintenance factor and is defined as the ratio of initial metre candles to the ultimate maintained metre-candles on the working plane. Its value is more than unity. 08. ABSORPTION FACTOR – In places where atmosphere is full of smoke and fumes, such as in foundries, there is a possibility of absorption of light. The ratio of total lumens available after absorption to the total lumens emitted by the source of light is called absorption factor. 09. BEAM FACTOR – The ratio of lumens in the beam of a projector to the lumens given out by lamp is called the beam factor. This factor takes into account the absorption of light by reflector and front glass of the projector lamp. Its value varies from 0.3 to 0.6 10. SPACE-HEIGHT RATIO (SHR) – It is defined as the ratio of horizontal distance between adjacent lamps and height of their mountings. The value of the ratio, in practice is between 1 and 1.5.

In this video I explore the possibility of making DIY sound absorption panels on a budget, later comparing them to much more expensive acoustic foam. The results are pretty amazing! There have been many comments pointing out that my test only measures transmission and not reflection, so is essentially unsuitable for my initial testing goal. While this is partly true, testing reflection is pretty difficult to do in a home environment, and the only way to do it that I can think of would be to spend a long time in the middle of a field with a powerful speaker and mic rig, which is really beyond the scope of what I was prepared to do for the video. My tests are not rendered pointless however - it would do no good to have only measured reflection, as the thinnest lightest material would have won (like foam), as nothing would have bounced back. Reflection and transmission need to be tested together to measure how much sound passes through, and how much sound is reflected back - this should give an indication of how much sound is absorbed by a given material. Regardless, only testing the transmission doesn't affect the outcome of the project at all, as any sound waves reflected by the panels themselves would have theoretically bounced off the wall anyway - again this is why reflection wasn't tested, as it doesn't matter so much for a panel setup (though would matter very much for a vocal booth). Open to hear any thoughts about it though! Keep up the great discussion. :)

Science with Dr. J A Series of 40 Episodes about Science Posted on YouTube in September, 2017 Episode 3 – Meet the Characters What is this about? This is the 3rd video in a series of 40 videos about science. The title of this Episode is “Meet the Characters”. In order to understand the Big Bang and our universe, Dr. J takes you to the basics, so you can understand certain terms and phenomena in nature, which will make it easier for you to comprehend many of the complex things he will later explain in subsequent episodes. He covers units of measure, speed, velocity, acceleration, density, pressure, momentum, force, energy, Einstein’s equation of E=mc2, atomic structure, nature of light and the electromagnetic spectrum, how infrared works, why objects have color, the Doppler Effect, red shift, how to read and write large and small numbers using the scientific notation, gravity and the four fundamental forces of nature (strong forces, electromagnetism, weak forces, and gravity). The Style Used in this and All Episodes: The best thing about this series is this: Dr. J does not lecture you. He tells it all as a story. It's unique, compelling, riveting, informative, fun, and exciting. His lectures are all supported with fantastic, quality, high resolution images and illustrations and graphs. Who is this Series Made for? Dr. J uses simple language, and his target audience is young people ages 12 to 22. So if you are a professional or a career scientist, this is a waste of time for you. This is by design a series for young people, with a very friendly style using simple words with minimal jargon. Keywords Dr. J highlights all keywords in every video, so that you can later identify them and research them and gain more in-depth understanding from other reliable sources. How to Watch this Series? This is a long Episode, so it is broken into two parts. This is Part 2, and if you have not yet watched the first one, please do. You should watch the Part 1 first. It is advisable to watch videos in sequence, because D. J builds your understanding of science step by step. Additional References At the end of this description, Dr. J will later on add some additional reference videos and reading to further enhance your experience and your journey of learning about your amazing natural world. Why did Dr. J Do This? Dr. J is passionate about science, passionate about teaching, and serious about wanting you, young people, to become scientifically literate, whether or not you plan to go into a science career later on in life.
