What is the cause of refraction of light?

State the laws of refraction of light. State at least three examples of refraction of light.

The refractive index of a medium is sqrt(3) . What is the angle of refraction, if unpolarizing light is incident on the polarising angle of the medium ?

What is meant by refraction of light?

State the Snell's laws of refraction of light.

When a light ray is incident on a medium of refractive index 4/3, reflected light is found to be 100% polarized. What is the angle of refraction in degrees? (tan 53^@ = 4/3) .

The laws of reflection or refraction are the same for sound as for light. The index of refraction of a medium (for sound) is defind as the ratio of the speed of sound in air 343 m//s to the speed of sound in the medium. What is the index of refraction (for sound) of water (v=1498 m//s) ? What is the critical angle theta , for total reflection of sound from water?

What do you understand by the term 'refraction of light'?

A ray of light falls on a transparent glass slab of refractive index 1.62 . If the reflected ray and the refracted rays are mutually perpendicular, what is the angle of refraction ?

State the laws of refraction of light. Explain the term 'absolute refractive index of a medium' and write an expression to relate it with the speed of light in vacuum.
