Question

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

Answer 1

Explain the term absolute refractive index of a medium and write an expression to relate it with the speed of light in vacuum. ... Laws of refraction states that: (1) The incident ray, the refracted ray and the normal to the interface of two media at the point of incidence all lie in the same plane.

Answer 2

Refraction: Bending nature of a light ray when it passes from one medium to other towards or away from the normal...
