Question

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

Answer 1

Absolute refractive index=Speed of light in vacuum/Speed of light in diamond
=$\frac{3,00,000}{1,24,000}$
=2.419...
=2.42 (approx)
Ans:The absolute refractive index of diamond is 2.42.

Answer 2

Guy's ur answer is

Absolute refractive index =speed of light in vaccum /speed of light in dimounds

3,00,000/1,24,000

= 2.419......

=2.49(approx)

Answer :The absolute refractive index of diamond if 2.42
