Answer 2

Answer:

b) incident ray..................

Explanation:

A reflected ray is a ray of light that represents the light reflected by the surface or the ray of light that bounces off the mirror.

An emergent ray is a ray of light which finally emerges out of the other medium back to the original medium.

An incident ray is a ray of light approaching the mirror or falling on the mirror.

A transmitted ray or a refracted ray is a ray of light that is transmitted into the second medium and undergoes a change of velocity and direction due to the interaction with the material medium in which it travels.
