Question

what is the refractive index of medium in which the speed of light becomes half of the speed of light in air

Answer 1

Answer:

Refractive Index of a medium (µ) = Velocity of light in vacuum / Velocity of light in the medium. Let the velocity of light in vacuum be v1 and velocity of light in the medium be v2. v1 /2 = v2. Hence µ = v1 / v2. = v1 / (v1 /2 ). = 2 Read more on Sarthaks.com - https://www.sarthaks.com/503878/i-on-entering-in-a-medium-from-air-the-speed-of-light-becomes-half-of-its-value-in-air
