Question

c) sini
11. Absolute refractive index for a given light in a given medium depends on
c) speed
d) both a and c​

Answer 1

Absolute refractive index =

speed of light in medium/

Speed of light in vacuum

.

Raise in temperature increases speed of light in medium as its optical density decreases. At the same time for different wavelength of incident light have different refractive index.

Refractive index can be written as n= λ m/ λ v

, where λ

v is the wavelength in vacuum and λ m is the wavelength of the medium.

Absolute refractive index of a material depends upon density and temperature of the material. It also depends upon the wavelength of the incident light.

its the answer....
