Question

17. Light enters from air into diamond which has a refractive index of 2.42. Calculate the speed of light in
diamond. The speed of light in air is 3.0×10^8m/s
​

Answer 1

Μ = Speed of light in air/speed of light in medium

=> 2.4 = 3 * 10^8/ speed of light in diamond

=> Speed of light in diamond = 3 * 10^8/2.4

=> 1.25 * 10^8 m/s
