This document discusses the properties of concave and convex mirrors. It explains that concave mirrors are made by silvering the outer surface, resulting in reflection from the hollow inner surface. Convex mirrors are made by silvering the inner surface, so reflection occurs from the outer bulging surface. The document then provides rules for ray diagrams with mirrors and describes how concave mirrors form real, inverted images in various positions of the object. Image formation by convex mirrors is also summarized, noting that convex mirrors always form virtual, erect images. Practice questions are included at the end.
