Convex mirrors – One point many rays
Light will reflect off any point on the surface of an object and travel in many directions. If you put a convex mirror in the way some of these light rays will enter all over the surface of the convex mirror.
A tree at a large distance from the convex mirror will pass light rays onto the convex mirror. A person standing nearby the convex mirror will be able to see a smaller version of the tree as follows (this will be explained later):
Each point on the object will reflect light rays to the convex mirror.
From every point the observer will receive sufficient rays of light from the convex mirror so that every part of the object facing the mirror will be seen.
