Concave and convex mirrors

Concave mirror is a spherical mirror whose reflecting surface is curved inwards. A Good example is the driving mirror of a car.

Convex mirror is a spherical mirror whose reflective surface is curved outwards. A good example of a convex mirror is a shaving mirror.

General demonstrations of convex and concave mirrors (curved mirrors:

Terms used in studying curved mirrors

  1. Centre of curvature (C):the center of the sphere of which a mirror is a part of.
  2. Radius of curvature (R): the radius of sphere of which a mirror is a part.
  3. Pole (P): the central point of the reflecting surface of spherical mirror (curved or convex mirror).
  1. Principal axis: the straight line joining the center of curvature (C) and the pole (P).
  2. Principal focus (F): the point O the principal axis where light rays tend to intersect. This point is between center of curvature and the pole.
  3. Principal axis: the straight line joining the center of curvature (C) and the pole (P).
  4. Principal focus (F): the point on the principal axis where light rays tend to intersect. This point is between center of curvature and the pole.
