Topics in Reflection of light at curved surfaces

1

Types of Spherical Mirrors and Basic Terminology

  • Spherical mirrors are curved mirrors that form part of a hollow sphere
  • Two types: Concave mirrors (curved inward like a cave) and Convex mirrors (curved outward like the back of a spoon)
  • Centre of curvature (C): Center of the sphere from which the mirror is cut
2

Laws of Reflection for Curved Surfaces

  • First law of reflection applies to all surfaces: angle of incidence = angle of reflection
  • Both angles measured from the normal at the point of incidence
  • For curved surfaces, normal direction changes at each point
3

Ray Diagrams and Image Formation

  • Three principal rays for concave mirrors: parallel ray, focal ray, center of curvature ray
  • Parallel ray reflects through focus
  • Ray through focus reflects parallel to axis
4

Mirror Formula and Magnification

  • Mirror formula relates object distance, image distance, and focal length
  • Valid for both concave and convex mirrors with proper sign conventions
  • Magnification indicates size and orientation of image relative to object

Key Concepts

Curved mirrors formed from portionsWhen parallel rays hit a concaveThree key rays help locate imagesThe relationship 1/f = 1/v +Magnification (m) = height of image/height
