Light travels through a liquid at 2.25e8 m/s. What is the index of refraction of the liquid?

Refractive index = 1.33

Explanation:

Refractive index is of a material explains how light passes through a medium. It is the ratio of speed of light in vacuum to the speed of light in the medium.

We know the speed of light in water is and there is a change iñ speed of light in every medium it passes (except when it passes through vacuum). The change in speed of light is known to be =

Given speed of light = 2.25*10^8 m/s

Formula for refractive index:

Where,

change in speed of light, c=

speed of light, v = 2.25*10^8 m/s

= 1.328

= 1.33

The liquid is water, and the index of refraction of water is 1.33

the answer is b
