Answer:
When light is reflected, the "outgoing" ray is also called the reflected ray.
Explanation:
when an light ray is incident on a boundary of two mediums it an reflect or refract.
reflected ray is the part of the ray that gets back with same mediu that it was coming from. angle of reflection and incident are equal . angle of reflection and incident are the angle made by the reflected and incident ray with the normal.
total internal reflection occurs when the incident angle is greater than the critical angle of pair of given medium and when light travels from denser to rarer medium . in total internal reflection ray gets reflected with no loss at all.
in refracted ray the the light ray passes to the other medium angle of incidence and refraction are not same.
