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.
