Concept explainers

When a light ray (termed as the incident ray) hits a surface and bounces back (forms a reflected ray), the process of reflection of light has taken place.

Sign Convention for Mirrors

A mirror is made of glass that is coated with a metal amalgam on one side due to which the light ray incident on the surface undergoes reflection and not refraction.

Textbook Question

Chapter 25, Problem 16CQ

When you focus a camera, you adjust the distance of the lens from the film. It the camera lens acts like a thin lens, why can it not be a fixed distance from the film for both near and distant objects?
