Key Topics to Revise

1

Reflection of Light

  • Light is a form of energy that makes objects visible
  • Luminous objects emit light (sun, candle, bulb), non-luminous objects reflect light
  • Reflection occurs when light bounces back after striking a surface
2

Plane Mirror and Image Formation

  • Plane mirror forms virtual, erect image of same size as object
  • Image distance = Object distance from mirror
  • Lateral inversion occurs (left appears as right)
3

Spherical Mirrors

  • Concave mirror: reflecting surface curves inward, converges light
  • Convex mirror: reflecting surface curves outward, diverges light
  • Important terms: pole (P), focus (F), center of curvature (C), focal length (f), radius (R)
4

Refraction of Light

  • Refraction is bending of light when passing from one medium to another
  • Occurs due to change in speed of light in different media
  • Light bends towards normal when entering denser medium
