Write true or false for this statement:
A concave mirror converges the light-rays, but a convex mirror diverges them.

Open in App

Solution

A concave mirror is a converging mirror as it bends the light rays closer to its principal axis. A convex mirror is a diverging mirror as it bends the light rays away from its principal axis.

Hence, the question statement is true.
