Question

The refractive index of Diamond is 2.42. If c is the speed of light in air, calculate the speed of light in diamond?

Answer 1

Answer:

The speed of light in diamond is 1.24 x 10^8 m/s.

Explanation:

speed of light in air = 3x10^8m/s

diamind refrative index=2.42

2.42=X x 3x10^8

x=3x10^8/2.42

= 1.239x10^8m/s

=1.24x10^8m/s
