Detailed Solution

The above statement is True.
Concave mirrors can be used as shaving mirrors as these types of mirrors produce an erect and magnified image.
When a spherical mirror is curved is painted towards the outward surface, this mirror is called a concave mirror. This mirror focuses the light rays on a flat mirror which is kept at a focal distance. The intensity of light gets increased due to convergence, and the reflection formed by the mirror can be seen through the eyepiece. A concave mirror is also be used as a condenser in a microscope.
