Question

The speed of the light in a diamond is 1,24,000 km/s. Find the refractive index of diamond if the speed of light in air is 3,00,000 km/s

Given: The speed of the light in a diamond is 1,24,000 km/s, the speed of light in air is 3,00,000 km/s

To find the refractive index of the diamond

Solution:

We know,

Refractive index of the medium=

Speed of the medium in air

Speed of light in air

⟹Refractive index of diamond=

124000km/s

300000km/s

=

124

300

=2.4
