Calculate the index of refraction for a medium in which the speed of light is 2.290 x 10^8 m/s?

The idex of refraction of the medium is 1.31.

Explanation:

the relationship between the index of refraction of a medium and the speed at which light travels is given by:

n = c/v

where n is the index of refraction, c is the speed of light and v is the speed of light in the medium.

n = c/v

= (3*10^8) / (2.290*10^8)

= 1.31

Therefore, the idex of refraction of the medium is 1.31.
