Question

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

diamond if speed of light in air is 3,00,000 km/s.​

Answer 1

Answer:

Answer. Ans:The absolute refractive index of diamond is 2.42.

Answer 2

Answer:

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
