Topics in Reflection of light at curved surfaces

1

1. Basic ideas and terms

  • A spherical mirror is a mirror with a curved reflecting surface.
  • A concave mirror is bent inwards and acts as a converging mirror.
  • A convex mirror is bent outwards and acts as a diverging mirror.
2

2. Image formation by concave mirror

  • A concave mirror forms different images at different object positions.
  • Object beyond C gives a real, inverted, diminished image between F and C.
  • Object at C gives a real, inverted, same-size image at C.
3

3. Sign convention and mirror formula

  • All distances should be measured from the pole.
  • Distances measured in the direction of incident light are positive.
  • Distances measured opposite to the direction of incident light are negative.
4

4. Numerical example and calculation method

  • An object 4 cm in size is placed 25 cm in front of a concave mirror of focal length 15 cm.
  • Under sign convention, f = -15 cm and u = -25 cm.
  • Using the mirror formula gives v = -37.5 cm.
