Answer 2

Answer:

Refractive index: It is defined as the bending of light rays while the light ray enters from one medium to another. It is denoted by the letter n and expressed as:

Where,

c is the speed of light with a certain wavelength in the air

v is the speed of light in the given medium

Following are the factors on which the refractive index is dependent:

:Nature of the medium

:Physical conditions

:Colour of the wavelength of light

Therefore, these are the factors that determine the refractive index.

Relative refractive index: When light travels from one medium to another medium, then the refractive index is known as the relative refractive index.

Absolute refractive index: When light travels from vacuum to another medium, then the refractive index is known as the absolute refractive index
