Question

refractive indices of media P, Q, R and S are p -1. 31, Q -1. 33, R-1. 52 and S -1. 50 in which of the four media the speed of light is maximum and minimum​

Answer 1

Answer:

Explanation:

refractive index = speed of light in vacuum / speed of light in medium

therefore lower the refractive index higher the velocity of light

hence in media P light has maximum velocity
