Overview

Light makes objects visible when reflected light enters the eyes. In transparent media, light is transmitted, and when it travels from one medium to another, it may bend. Reflection explains image formation by mirrors, while refraction explains bending of light at the boundary of two media. Spherica

Key Concepts

Light reflected from a polished surface

Light reflected from a polished surface follows two laws: the angle of incidence equals the angle of reflection, and the incident ray, reflected ray,

An image formed by a plane

An image formed by a plane mirror is always virtual and erect. It is equal in size to the object, appears as far behind the mirror as the object is in

A concave mirror has a reflecting

A concave mirror has a reflecting surface curved inwards, while a convex mirror has a reflecting surface curved outwards. The pole is the centre point

For spherical mirrors of small aperture

For spherical mirrors of small aperture, the radius of curvature is twice the focal length, so R = 2f. The principal focus lies midway between the pol

A concave mirror can form real

A concave mirror can form real or virtual images depending on object position. At infinity the image is at F, beyond C it forms between F and C, at C
