What is refractive index?
Asked by parineeta0703 | 01 Aug, 2021, 01:44: PM
answered-by-expert Expert Answer
Refractive index of a medium is the ratio of velocity of light in air/vacuum to velocity of light in that medium  .
 
if velocity of light in medium is v and velocity of light in air/vacuum is c , then refractive index n of medium is given as
 
n = c / v

Can the angle of refraction in denser medium be more than the critical angle for the pair of media when the light ray is travelling from rarer to denser medium?

(a) Choose the correct statement with respect to Refraction of light [1] 1. The colour always changes when light enters from one optical medium to another. 2. Absorption of light when it strikes the surface of a medium is refraction. 3. Speed of light changes when it enters from one optical medium to another of different optical density. 4. Speed of light does not change when it enters from one optical medium to another of different optical density.
