Answer:

C) Index of refraction

Step-by-step explanation:

Index of refraction also known as refractive index is defined as speed of light in a vacuum divided by the speed of light in a given material.

The formula for Index of refraction is:

n = c ÷ v

where n represents Index of refraction,

c represents speed of light in a vacuum,

v represents speed of light in a given material.

The speed and direction of light changes when it moves from one medium to another. The change in direction is basically called refraction.
