Name two factors on which the refractive index of a medium depends? State how does it depends on the factor state by you.

Solution:

The following are the elements that influence a medium’s refractive index:

(i) Medium nature (e.g. μg = 1.5, μw = 1.33): The lower the speed of light in the medium compared to air, the higher the refractive index of the medium.

(ii) Physical conditions, such as temperature: As the temperature rises, the speed of light in the medium rises, lowering the refractive index of the medium.
