# define the principal focus of a convex mirror

The principal focus of a convex mirror is the point on the principal Axis from which all the incident rays parallel to principal Axis appear to come after reflection from the convex mirror

The reflected rays appear to come from a point on the principal axis. And this point is called the principal focus of the convex mirror.

The parallel rays reflect and appear to meet at a point on the principal axis. This point is called principal focus of convex mirror

what is "diverzz"?

The principle focus of convex mirror is that point at which rays parallel to the principal axis appear to meet. I have used "appear to meet" because in case of convex mirror only virtual image is formed.

The principle focus of a concex lens

A ray is a parallel of the principle axis and at point the principle focus after passes through the convex lens. This phenomeno is called the principle focus of a covex lens.
