Detailed Solution

The above statement is true.
A medium's refractive index is inversely proportional to its velocity of light. As a result, the Refractive index is affected by the speed of light in a given medium. The refractive index of a medium is the ratio of the speed of light in air or vacuum to the speed of light in another medium. The Refractive index is denoted by the Greek letter

μ

.
It can be written as

μ = \frac{Speed of light in air or vacuum}{speed of light in the medium}
