Refractive index `(mu)` of a medium depends upon

Options

A. temperature of the medium
B. wavelength of the incident light
C. nature and physical state of the medium
D. all the above

Answer

D

Explanation

Refractive index `(mu)` of a medium depends on the nature of medium, temperature (T) of medium, density `(rho)` of medium, physical state of medium and wavelength `(lamda)` of incident light.
Tou may remember:
(i) `muprop1/T`
(ii) `muproprho`
(iii) `muprop1/lamda^(2)`
