Question

What is the refractive index of the medium in which light enters from air and

travels with the speed of 2x108

m/s?(given that the speed of the light in air is

3x108m/s.​

Answer 1

Answer:

refractive index = speed of light in air/speed of light in given medium

$= \frac{3 \times {10}^{8} }{2 \times {10}^{8} } \\ = \frac{3}{2} \\ = 1.5$

HENCE the refractive index of the medium is 1.5

Answer 2

Explanation:

Refractive index = velocity of light in air/ velocity of light in the other medium

n = 3 × 10^8 / 2× 10^ 8

n = 1.5
