The index of refraction of the medium where the speed of light is 1.24× 10⁸m/s, is 2.42.
To find the answer, we need to know about the relation between the refractive index and velocity of light.
What's the the expression of refractive index of a medium in term of velocity of light?
- Refractive index of any medium (n)= C/V
- C= speed of light in vaccum which is 3×10⁸ m/s , V = velocity of light in the medium
What's the refractive index of a medium in which speed of light is 1.24 x 10⁸ m/s?
Refractive index of the medium =
3×10⁸/1.24 x 10⁸
= 2.42
Thus, we can conclude that the refractive index of the medium is 2.42.
