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

When an object is placed 12 cm away from a concave mirror, the height of its
upright image is double its height. What is the focal length of the mirror?
f = 24 cm
O f= -8 cm
O f = 28/3 cm
f = 8 cm
f = 28 cm
