2.5 The field of vision

Determine the field of vision of an observer facing a mirror, after conducting experiments.

Uses

Make-up kits often include three mirrors: a plane mirror, a concave mirror, and a convex mirror. Each has its own special use. The convex mirror is used to see the whole face. The concave mirror is used for detail, such as applying eyeliner. Finally, the plane mirror gives us a undistorted image of part of the face.
