# Reflection convex mirrors

A convex mirror obeys the three laws of reflection (see these rules explained under "Plane or flat mirrors").

The key element of these rules is:

"The angle between the incident ray and the normal is equal to the angle between the reflected ray and the normal."

So we now know that any ray of light that strikes a convex surface will reflect as follows:

The angle `thetai` and `thetar` will always be the same.
