What happens when any ray of light strikes a concave mirror, after passing through its focal point?
a)the reflected ray travels parallel to the vertex.
b)the reflected ray passes through the principal axis.
c)the reflected ray passes through the center of curvature.
d)the reflected ray travels parallel to the principal axis.

Option (D)

Explanation:

The rules to draw the ray diagrams for concave mirror are given below:

1. When a ray of light incident on the pole of concave mirror at an angle of incidence, then after reflection, the angle of incidence is equal to the angle of reflection.

2. When incident ray of light passes through the centre of curvature of the mirror, then the reflected ray retraces its path.

3. When the incident ray of light passing through the focus of the concave mirror, then after reflection the reflected ray becomes parallel to the principal axis and vice versa.
