The direction of ray of light incident on a concave mirror is shown by $PQ$ while directions in which the ray would travel after reflection is shown by four rays marked $1, 2, 3$ and $4$. Which of the four rays correctly shows the direction of reflected ray?

Solution and Explanation
In spherical mirrors, the incident ray passing through the focus of mirror becomes parallel to principal axis after reflection, which is shown by ray $2$.
A spherical mirror is a mirror which has been cut out of a spherical surface.
There are two kinds of spherical mirrors:
Convex Mirror
Concave Mirror
Spherical Mirrors
Concave Mirror
Concave mirrors are also called converging mirrors, because in these types of mirrors, light rays converge at a point after impact and reflect back from the reflective surface of the mirror.
Convex Mirror
The convex mirror has a reflective surface that is curved outward. Regardless of the distance between the subject and the mirrors, these mirrors are "always" virtual, upright and reduced.
