Overview

Reflection of light is the return of light into the same medium after striking a surface. It is the reason objects are seen, because non-luminous objects become visible when they reflect light into the eyes. Reflection may be regular on smooth, polished surfaces and irregular on rough surfaces. Plan

Key Concepts

The return of light into

The return of light into the same medium after striking a surface is called reflection. A plane mirror does not reflect 100% of the light falling on i

Regular reflection occurs on smooth

Regular reflection occurs on smooth and polished surfaces, such as a plane mirror. Irregular reflection occurs on rough surfaces, such as a wall or a

The angle of incidence is equal

The angle of incidence is equal to the angle of reflection. The incident ray, reflected ray and the normal at the point of incidence lie in the same p

A plane mirror forms a virtual

A plane mirror forms a virtual, erect image of the same size as the object. The image appears as far behind the mirror as the object is in front of it

The interchange of left and right

The interchange of left and right sides in the image of an object in a plane mirror is called lateral inversion. Letters such as A, H, I, M, O, T, U,

Learning Objectives

  • Understand the meaning of reflection of light and the difference between regular and irregular reflection.
  • State and apply the two laws of reflection.
  • Describe the formation and characteristics of images in a plane mirror.
  • Explain lateral inversion and its common examples.
  • Find the number of images formed by two plane mirrors placed at different angles.
