Concept explainers

Applications Of Reflection Of Light

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.

Question

If a concave mirror has a focal length of 20 cm, at which object distance will an image smaller than object be formed on the screen?
O 15 cm
O 40 cm
30 cm
O 50 cm
