Question

will the velocity of light be same in all media

Answer 1

No, the velocity of the light will not be same in all media. The denser the medium, the slower light travels. It travels the maximum velocity in air or vacuum.

Hope it helps!!!

Answer 2

Answer:

No, Light is slowed down in transparent media such as air, water and glass. The ratio by which it is slowed is called the refractive index of the medium and is usually greater than one. ... When people talk about "the speed of light" in a general context, they usually mean the speed of light in a vacuum.
