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.
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.
