In concave mirrors;

Rays coming parallel to the principal axis pass from the focal point

Rays coming from the focal point travel parallel to the principal axis

Ray coming from the center of curvature turn back on itself

Ray hits the mirror at vertex, it reflects with the same angle it does with principal axis

If the object is placed between focal point and the vertex then image is virtual, behind the mirror, erect

and larger than the object. In other conditions, image is real and inverted.

In convex mirrors;

Light rays follow the same path given above for concave mirrors.

Image of the object is always located between focal point and vertex, behind the mirror, and it is

virtual and magnified in size.
