Question

velocity of the light in air 3x10 to the power 8 m/swhile its velocity in medium is 1.5 x 10 to the power 8 metre per second then what refractive index of medium​

Answer 1

Answer:

2

Explanation:

Velocity of light in air = 3*10^8 m/s

Velocity of light in medium = 1.5 * 10^8 m/s

Refractive index of that medium = Velocity of light in air/Velocity of light in medium

= 3*10^8/1.5*10^8

= 2
