diamond if the speed of light in air is 3,00,000 km/s. (AS)
(Ans: 2.42)
Refraction at Plane Surfaces​

Answer 1

Explanation:

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= 300000km/s/124000km/s

=300/124 =2.4
