Question

31.If the speed of light in vaccum is 300000000 m/s and speed of light inmedium is 140000000 m/s .find the absolute refractive index of the medium.​

Answer 1

Answer:

The absolute refractive index of a medium is 2.14.

Explanation:

The speed of light in vaccum,  

The speed of light in a medium,  

Let n is the absolute refractive index of a medium. It is given by the ratio of speed of light in vaccum to the speed of light in a medium. So,

So, the absolute refractive index of a medium is 2.14.
