Detailed Solution

The above statement is True.
A spherical mirror consists of the shape of a piece cut out of a spherical surface. There are two kinds of spherical mirrors: convex and concave.
When incident upon concave mirror via focus, the reflected ray becomes parallel to the principle axis after reflection. A light ray passing through the focus of a concave mirror becomes parallel to the principal axis after reflection. Light rays change direction when they reflect off a surface, move from one transparent medium into another, or travel through a medium whose composition is continuously changing.

When a ray of light incidents upon a plane mirror, the light ray gets reflected off the mirror. After reflection, there is a change in the direction of the light rays. The convention used to express the direction of a light ray is to indicate the angle that the light ray makes with a normal line drawn to the surface of the mirror.
