Question

The veloity of light is different in different media.( true or false )​

Answer 1

TRUE !

VELOCITY OF LIGHT IN VACUUM IS 3×$10^{8}$

WHEN IT ENTERS ANY MEDIUM, FOR EXAMPLE A PRISM , IT CHANGES AND BECOMES 2.2×$10^{8}$ RESPECTIVELY.

HENCE VELOCITY OF LIGHT IS DIFFERENT IN DIFFERENT MEDIA.

HOPE THIS HELPED !

HAVE A GOOD DAY !

Answer 2

I don't know what is veloity but if it is velocity see the answer . media other than vacuum.

But light does not slow down in media due to absorption and re-emission.

Absorption features are typically very spectrally narrow. Materials will only absorb a narrow band of wavelengths. The index of refraction is very broad over long regions of the spectrum. Also, if it were correct to use the absorption model, then index of refraction would depend only on the type of material, which (if we take the case of carbon) is not the case. Diamond (n=2.4) and soot (n=1.1)are both made of carbon,
