Answer:

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.
