Question

a ray of light travels from a medium of refractive index 4/3, tgen the speed of light ray in medium is (Given, speed of light in air, c=3*1000000000 m/s).​

Answer 1

Answer: 2.25*10^8

Explanation: let the speed in unknown medium be "x".

We know,

μ = speed of light in vacuum/speed of light in medium.

According to problem,

4/3 = 3*10^8 / x

4x = 9*10^8

x = 9*25*10^6

x = 2.25 * 10^8.

The speed of light in given medium= 2.25 * 10 ^ 8.
