Question

The figure shows two incident rays $A$ and $B$ being reflected by a mirror as $A^{\prime }$ and $B^{\prime }$. The mirror is a

• A. plane mirror
• B. convex mirror
• C. concave mirror
• D. convex mirror or a concave mirror

Answer 1

The correct option is A plane mirror

We know that concave mirrors are known as converging mirror because it converges parallel rays at a point.
Similarly, convex mirrors are known as diverging mirror because it diverges parallel rays.
But here, the rays remain parallel after reflection. This is possible in case of plane mirror only.


Hence, the mirror is a plane mirror.
