The speed of ...

Question

The speed of light is ________ in different optical media.

Open in App

Solution

The speed of light depends on the 'refractive index' of the medium.
More is refractive index, lesser is speed of light.
Different optical medium exhibits different refractive index, therefore the speed of light is different in different optical media.

Hence, the speed of light is different in different optical media.
