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