What are the two types of curved mirror called?
they are called concave mirror ... mirrors whose center bulges out are called convex, and can reflect a wider view than a flat mirrored surface, but the objects are "larger than they appear", and also "closer than they appear." These are most often seen on right hand mirrors on vehicles, to help minimise blind spots. mirrors whose center is recessed are called concave (remember the term by thinking of a shallow cave.) Depending upon how close you are to the mirror's focal point, objects appear larger than they really are, or upside down. These are often seen in makeup mirrors so you get a clearer view of your face when shaving or applying makeup. Combinations of both convex and concave mirrors are seen in funhouses of amusement parks, to make the viewer look skinnier and taller, shorter and fatter, or even upside down.
