Question

factors on which refractive index depends

Answer 1

Nature of material

Physical conditional

Wavelength of light used

Answer 2

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.
