Question

the angle of refraction is equal to angle of incidence, when the light ray is traveling​

Answer 1

Explanation:

Angle of incidence is equal to angle of reflection not refraction.

Option b and c are correct

Light not only bounces off surface it goes through some of them often slowing down and changing direction in the process called refraction. It occurs at the point where light travels from one medium to another of different density. Refraction produces mirages and rainbows.

When a ray of light (i.e., the incident ray) goes from rarer to denser medium, the ray (refracted ray) bends towards the normal in the denser medium.

incident ray passes from rarer to denser

If ray of light travels from denser to rarer medium the refracted ray bends away from the normal.

incident ray passes from denser to rarer

Answer 2

Answer:

from denser to rarer medium
