What to Focus On

  • Light makes objects visible.
  • Reflection is the bouncing back of light from a surface.
  • Smooth surfaces give regular reflection.
  • Plane mirror images are virtual, erect, and same in size.
  • Object distance equals image distance.
  • Plane mirrors show lateral inversion.
  • Concave mirrors reflect from the inner curved surface.
  • Convex mirrors reflect from the outer curved surface.
  • Pole, focus, centre of curvature, and principal axis are key terms.

Common Mistakes to Avoid

Reflection means the light disappears after hitting a surface.

In reflection, the angle of incidence and angle of reflection are not equal if the surface is smooth.

A plane mirror forms a real image that can be caught on a screen.
