Question

What is refractive index in simple words?​

Answer 1

Answer:

the change of direction of light in different medium such as in water

Answer 2

Answer:

Refractive index:

The ratio between the speed of light in medium to speed in a vacuum is the refractive index.

Formula:

The refractive index of a medium is calculated by the formula:

n = c/v

where c is the speed of light in vacuum and v is the speed of light in the medium.
