Define Principal Focus of a Convex Mirror

The primary focus than a convex mirror is defined as the light beams that converge just on the principal axis following reflection off a wall mirror and seem to be parallel to a principal axis. They are in genuine meetings or appear to be in virtual meets. Just on screen, the virtual image does not take shape.

After reflection, incoming rays that are parallel to the primary axis appear to deviate from a common point just on the principal axis, which is referred to as the primary emphasis of a reflective surface. It’s commonly symbolised with the letter F.
