Refraction and Reflection of Light
IO incident ray OR l reflected ray OR refracted ray The diagram shows how the light gets refracted when it is traveling from one optical medium to another. Like reflection, refraction of light takes place according to certain law..
Refraction of Light
Let us now see what happens when a ray of light is incident on the boundary separating the two mediums having different densities. A part of the light gets reflected and rest of the light changes its direction as it enters the second mediu..

In the previous chapter we have seen how light gets reflected when it is incident on a surface. Now let us see what happens when a ray of light traveling from one medium to another medium of different densit..

Like light, sound waves also obey the laws of reflection and refraction. For sound waves to reflect, we need extended surface or obstacle of large size. For example, the rolling of thunder is due to successive reflections from clouds and land surfac..
Total Internal Reflection
If the angle of incidence of a ray of light traveling from a denser medium to a rarer medium is greater than the critical angle for the two media, then the ray is reflected into the denser medium and this phenomenon is described as total internal reflection. ..
If the angle of incidence of a ray of light traveling from a denser medium to a rarer medium is greater than the critical angle for the two media, then the ray is reflected into the denser medium and this phenomenon is described as total internal reflection. ..Total Internal Reflection
Let us consider a ray of light passing from glass to air, that is from a denser medium to a rarer medium. The figure shows that for a small angle of incidence, major part of the incident light is refracted and a small portion is reflected. The refractedh..
Brewster's Law (Polarization by Reflection)
When unpolarised light is incident at polarizing angle i p on an interface separating air from a medium of refractive index m then, m = tan i p When the light is incident at polarizing angle ip, the reflected component along OB and refractedh..

Total Internal Reflection - Total Internal Reflection Consider an object at O in a denser medium. A ray of light incident normally to XY goes undeviated along AB. As the angle of incidence increases, the angle of refraction also increases. On increasing ..

Mirage is an optical illusion, which occurs usually in deserts on hot summer days. On such a day, temperature of air near the earth is maximum and hence is rarer or lighter. The upper layers of air, which are relatively cool, are denser. A ray of light from the top of a tree travels fro..

Tutor has given me a lot of good advise for my study. They has the package to be the best and the best teachers! they are not just have the teaching skills and understanding the subject matters as well. Thank you.
Ohhhhhhh wow soooo speechless i loved it this tutor will forever be in lovely nice sweet heart i love u tutorvista - Liam
Turtors are so good, and patient and most important knows their stuff. They really tutor in a very professional way. Their system is unique and they really knows how to explain and made sure you undertand. They even put stuff from a book into the white board, just to show me how the process of my question - Paul
Excellent! Very interested session and learning new words make me more think and feel good.-Savannah
