n=speed of light in vacuum /speed of light in medium
n=c/v
2.42=3x10^8/speed of light
Speed of light =3x108/2.42
=1.25x108 m/s
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 x 108ms−1.
Refractive index of diamond is 2.42. Calculate the speed of light in diamond.
The speed of light in diamond is 125,000 km ms−1. What is its refractive index? (Speed of light in air = 3 ×108ms−1 )
The refractive index of diamond is 2.42 what is the meaning of this statement in relation to the speed of light.
