Question

name two factors in which refractive index depends on?

Answer 1

1:-wave length of light passing through it

2:-nature of the surrounding medium

3:-also temperature

Answer 2

Two factors are :

• wavelength

• optical density

Refractive index depends upon the following factors :

(i) Refractive index is inversely proportional to the optical density of the medium .

(ii) Refractive index is inversely proportional to the temperature of the medium.

(iii) It is inversely proportional to the wavelength of the ray.

Note :

Optical density depends upon the material of the body.
