Question

the speed of the light in a diamond is 124000 kilometre per second find the refractive index of diamond in the speed of the light in air is 3 lacs kilometre per second​

Answer 1

Answer:

Speed of light in diamond = 1.24x10^8m/s

Speed of light in vacuum = 3 x 10^8 m/s

Refractive index n = Speed of light in vacuum/ Speed of light in diamond

Refractive index n = (3x10^8m/s)/(1.24x10^8m/s)

= 2.42

Refractive index of diamond n = 2.42
