Question

To which point will the rays return if a plane mirror is kept in contact with convex mirror

Answer 1

Light rays that come towards the mirror from far away are essentially parallel, but when they hit the mirror they are reflected in all directions. However, there is a virtual focal point on the other side of the mirror if we follow them back into the mirror.

Answer 2

At focus as convex mirror forms virtual image and image is at infinity with respect to it as it is placed in contact with plane mirror
