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.

it is true because as we rotate around the way we rotate makes day come and because the moon is rotating around the earth that's what makes it night come. hope this .
