Key Topics to Revise

1

Nature of Light and Reflection

  • Light travels in straight lines in a homogeneous medium
  • Objects become visible when light reflects from them and enters our eyes
  • Highly polished surfaces like mirrors reflect most of the light falling on them
2

Spherical Mirrors

  • Concave mirror: reflecting surface curves inward toward center of sphere
  • Convex mirror: reflecting surface curves outward away from center of sphere
  • Key terms: Pole (P), Center of curvature (C), Principal axis, Principal focus (F), Focal length (f)
3

Image Formation by Spherical Mirrors

  • Concave mirror can form both real and virtual images depending on object position
  • Convex mirror always forms virtual, erect, and diminished images
  • Real images can be obtained on screen; virtual images cannot
4

Refraction of Light

  • Refraction occurs when light passes obliquely from one transparent medium to another
  • Light bends toward normal when going from rarer to denser medium
  • Light bends away from normal when going from denser to rarer medium
