Detailed Solution

The angle of reflection, when a light ray passing through the

2 F

of a spherical mirror, after reflection, returns along the same path. Then the angle reflection is

0 ° .

When a ray of light passes through the centre of curvature of a spherical mirror. The ray passing through the centre of curvature after returning to the same path as the ray incident with the normal to the mirror on the reflector surface after reflection is normally incident to the mirror. Therefore, the angle of reflection is zero. Therefore, the ray passing through the centre of curvature is a normal incident in the mirror.
