Question

Write refractive index in 2 different forms

Answer 1

refractive index can be written in 2 different forms:

1. Absolute refractive index

2. Relative refractive index

Answer 2

Answer:

Refractive index of a medium with respect to air is the ratio of the velocity of light in air to the velocity of the light in the medium. It is also the ratio of the refractive index of the medium with respect to vacuum to the refractive index of air with respect to vacuum.

Explanation:

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:

$n=\frac{c}{v}$

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.
