When light passes from one medium into another medium, then the physical property which does not change is:

When light passes from a denser medium to a rarer medium

When light passes from one medium to other medium then the frequency of light

When light passes from one medium to another, there is a change in

When a ray of light travel from one medium to other then the physical quantity which does not change is

Assertion : When light passes from one medium to another of different density the only quantity which is unchanged is its wavelength . Reason : The wavelength of light is not related to the refractive index of the medium .

When light passes from one medium to another medium, which one of these quantities, remains unchanged.
