Overview

Curved mirrors form images by reflection of light from spherical surfaces. A concave mirror bends inward and converges reflected rays, while a convex mirror bends outward and makes reflected rays diverge. The chapter connects the laws of reflection, ray diagrams, image formation, the mirror formula,

Key Concepts

A spherical mirror is a mirror

A spherical mirror is a mirror with a curved reflecting surface. A concave mirror is bent inward and acts as a converging mirror. A convex mirror is b

The pole is the geometrical centre

The pole is the geometrical centre of the mirror. The centre of curvature is the centre of the sphere of which the mirror is a part. The principal axi

For a concave mirror

For a concave mirror, parallel rays converge at the focus after reflection. For a convex mirror, reflected rays appear to diverge from the focus. The

The radius of curvature is

The radius of curvature is the distance from the pole to the centre of curvature. It is related to focal length by R = 2f.

A real image is formed by

A real image is formed by the actual intersection of reflected rays and can be caught on a screen. A virtual image is formed by extending reflected ra

Learning Objectives

  • Understand the basic parts of a spherical mirror: pole, centre of curvature, principal axis, focus, focal length, and radius of curvature.
  • Apply the first law of reflection to curved surfaces.
  • Use ray diagrams to find the nature, position, and size of images formed by concave and convex mirrors.
  • Distinguish between real and virtual images.
  • Use the mirror formula and magnification formula with correct sign convention.
