Key Topics to Revise

1

Reflection of Light and Spherical Mirrors

  • The angle of incidence equals the angle of reflection.
  • The incident ray, the normal, and the reflected ray lie in the same plane.
  • A plane mirror forms a virtual, erect image that is laterally inverted and equal in size to the object.
2

Refraction of Light and Refractive Index

  • Refraction is the bending of light when it passes from one transparent medium to another.
  • Light bends towards the normal when it goes from a rarer medium to a denser medium.
  • Light bends away from the normal when it goes from a denser medium to a rarer medium.
3

Lenses and Image Formation

  • A lens is a transparent material bounded by at least one spherical surface.
  • A convex lens is thicker at the middle than at the edges and converges light rays.
  • A concave lens is thinner at the middle and thicker at the edges and diverges light rays.
