Question

state the law of reflection 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​

Answer 1

speed of light in vacuum is 3×10-6

Absolute refractive index of a medium is defined as the ratio of the velocity of light in vacuum to the velocity of light in the medium. If c is the velocity of light in vacuum and v in the medium, then n = c/v.

Answer 2

Answer:the backward motion of light on falling on a polished surface is reflection.

Law of reflection

Angle i= angle r

Incident ray, reflected ray and normal at the point of incidence lie on the same plane.

Absolute refractive index is the speed of light in vaccum by speed of light in medium

Explanation:

Absolute refractive index =c/v
