Key Topics to Revise

1

Basic Concepts of Reflection

  • Reflection is the return of light into the same medium after striking a surface
  • We see objects because they reflect light which reaches our eyes
  • Regular reflection occurs on smooth, polished surfaces like mirrors
2

Laws of Reflection

  • First Law: Angle of incidence equals angle of reflection (∠i = ∠r)
  • Second Law: Incident ray, reflected ray, and normal lie in the same plane
  • These laws apply to all types of reflecting surfaces
3

Image Formation by Plane Mirror

  • Images formed are virtual, erect, same size, and laterally inverted
  • Image distance behind mirror equals object distance in front
  • Virtual image cannot be obtained on screen but can be seen by eye
4

Multiple Images in Mirror Systems

  • Two parallel mirrors produce infinite images
  • Two perpendicular mirrors produce exactly 3 images
  • For mirrors at angle θ: Number of images = (360°/θ) - 1 when n is even
