Question

Write the two factors on which the refractive index of a medium depends.

Answer 1

Refractive Index:

Refractive index $\left(\mu \right)$ is defined as that it is a measurement of optical density (density of optical medium).

For example : $\left(\mu \right)$ of water is $1.33$.

Refractive index of a medium depends on two factors:

1. Nature or optical density of the medium: More optical denser medium has a larger value of the refractive index.
2. Physical conditions for example temperature: Refractive index of a medium decreases with an increase in the temperature of the medium.
