Question

what happens when light goes from vacuum to another medium??

Answer 1

Answer:

when light goes from vacuum to other medium it bend towards the normal or we can say as the refractive indexes differs the light bends .

Answer 2

Answer:

The bending of light as it passes from one medium to another is called refraction. The angle and wavelength at which the light enters a substance and the density of that substance determine how much the light is refracted. ... The bending occurs because light travels more slowly in a denser medium.
