Question

The index of refraction (n) for a liquid can also be defined as the ratio of the _________ (i) in air to the ______ (r) in the medium.

Answer 1

The index of refraction for a liquid is the ratio of the speed of light in air to the speed of light in the medium.

Step-by-step explanation:

The index of refraction (n) for a liquid can also be defined as the ratio of the speed of light in air to the speed of light in the medium.

This means that the index of refraction is a measure of how much the light slows down as it passes through the liquid compared to air.

For example, if the index of refraction of a liquid is 1.5, it means that light travels 1.5 times slower in the liquid than in air.
