Question

the speed of light in a medium of absolute refractive index is 1.5 is 2 x 10^8 m/s .
what is the speed of light in vacumm

give step by step calculation
or else answer will be reported

Answer 1

Answer:

3 x 10^8

Explanation:

Given :

speed of light in a medium = 2 x 10^8

absolute refractive index = 1.5

Absolute refractive index =

speed of light in vacuum / speed of light in a medium

1.5 = speed of light in vacuum / 2 x 10^8

1.5 x 2 x 10^8 = speed of light in vacuum

speed of light In vacuum = 3 x 10^8

Thanks

Answer 2

Answer:

3×10^8 m/s.
