Description

REFLECTION OF LIGHT FROM A PLANE SURFACE

Reflection of point object and line objects

REFLECTION FROM A PAIR OF MIRRORS

Number of images formed is given by the formula n = 3600/θ where θ  is the angle between 2 mirrors

REFLECTION FROM SPHERICAL MIRRORS

MAGNIFICATION AND MIRROR FORMULA

Mirror formula : 1/f = 1/v + 1/u

USES OF SPHERICAL MIRROR

CONVEX MIRROR USES

  1. rear-view mirror in automobiles.
  2. Reflector for parking lots
  3. In street lamp as reflector

CONVEX MIRROR USES

  1. Shaving mirror
  2. Dentist head mirror
  3. In torch as reflector
