Object between F and P. Image behind mirror, virtual, erect and magnified.

Convex mirror

The diverging reflected rays appear to meet at F when produced backwards ; F is the principal focus.

PF = f = focal length
PC = R = Radius of curvature
In a similar way as the concave mirror, it can be shown that f = R/2 for a convex mirror.

Image Formation in Convex Mirror

Object at any position. Image between P and F on the other side, virtual, erect and diminished
