Abstract
What is the real behaviour of the spherically concave mirror which we were taught in school focuses a parallel beam to a point What is the accuracy and range of its focussing behaviour and what happens outside that range How do we relate this behaviour to the measurable dimensions of the mirror This article presents answers to these questions using simple geometry and algebra
