Question

Calculate the speed of light in a diamond if the refractive index is 2.4.

Answer 1

Answer:

index = speed of the light in air / speed of the light in medium. Speed of light in medium = 3×10^8 / 2.4 m/s. = 1.25 × 10^8 m/s

Answer 2

Answer:

1.25×10^8m/s

Refractive index of diamond = 2.42

Speed of light in air=3.0 x108m/s

We know that

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

2.42 = 3 x 108/speed of light in diamond
