Explanation:

When a light falls on 52° to the mirror, the angle of incidence (i) is calculated by

i=90°-angle at which the light impacts with the mirror which in this case is 52°.

Hence the angle of incidence is 38° to the normal.

The angle of incidence and the angle of reflection to the normal is the same when the mirror is horizontally placed.

Hence the angle between the normal and angle of reflection is 38
