Question

Light enters from air to diamond with refactive index 2.42. what is speed of light i diamond.(C=3×(10)8m/s​

Answer 1

Answer:

1.2×10^8m/s

Explanation:

By applying formula

n=c/v

v=3×10^8/2.42

v=1.2×10^8m/s

Hope this helps you.

Answer 2

Answer: 1.24×10^8m/s

Explanation:Speed of the light in air = 3 × 10^8 m/s

Given Refractive index of diamond = 2.42

Refractive index = speed of the light in air / speed of the light in diamond.

2.42 = 3 × 10^8 m/s / Speed of light in medium

Speed of light in diamond = 3×10^8 / 2.4 m/s.

= 1.24 × 10^8 m/s.
