Overview

Light is a form of energy that makes objects visible. It travels as rays, undergoes reflection and refraction, forms images in mirrors and lenses, disperses into colours, and helps explain how the human eye works. The chapter connects everyday observations such as mirrors, spectacles, rainbows, and

Key Concepts

Reflection is the bouncing back

Reflection is the bouncing back of light after it falls on a surface. A smooth shining surface that reflects most of the incident light is called a mi

A plane mirror forms a virtual

A plane mirror forms a virtual, erect image of the same size as the object. The image is formed behind the mirror at the same distance as the object i

A convex mirror reflects from

A convex mirror reflects from the bulging surface and always forms a virtual, smaller image between the pole and focus. A concave mirror reflects from

For spherical mirrors

For spherical mirrors, the relation between focal length, image distance and object distance is 1/f = 1/v + 1/u. Magnification is the ratio of image s

Refraction is the bending of light

Refraction is the bending of light when it passes obliquely from one medium to another. Light bends towards the normal when it enters a denser medium

Learning Objectives

  • Understand reflection of light and its laws
  • Describe image formation in plane and spherical mirrors
  • Use mirror formula and magnification for mirrors
  • Understand refraction of light and refractive index
  • Describe lenses and image formation by convex and concave lenses
