Question

1. What will be the path of refracted ray for a Ray of light incident normally on the

interface between the two media?​

Answer 1

Answer:

When light enters a denser medium, the refracted ray moves towards the normal line. ... A ray of light is incident at 60° on a glass - air interface.

Answer 2

Explanation:

Adding to the answers…Snell’s law explains well. But, Have you not wondered to know the difference between same medium and different media? If a light is incident normally on a surface where the other surface is also the same as the first one, even then, the light doesn't bend. The difference you can observe in the wave length. If it is same media, there won't be any change in the wave length. If they are different media and light is incident normally, the velocity of the light changes thus the wave length. (Use the refractive index formula n = c/v and v=freq × wavelength.) Also, look at the concepts like reflection and Transmission.
