Curved mirrors

A curved (spherical) mirror is part of the surface of a ball. A concave mirror, reflecting on its hollow side, brings parallel rays together at its focus; an object between the mirror and the focus gives an upright, bigger, virtual image (a dentist's mirror), and one beyond the focus gives an upside-down real image that can fall on a screen. A convex mirror, reflecting on its bulging side, spreads rays out and always gives an upright, smaller, virtual image with a wide view (a car's side mirror, a mirror at a blind bend).

You can tell concave and convex mirrors apart, find a concave mirror's focus, say what image each gives for a near and a far object, tell real from virtual images, and say why each is used where it is.
