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

An object is placed 40 cm in front of a thin lens. If an image forms at a distance 120 cm from the lens, on the opposite side as the object, what is the focal length of the lens, in cm? (Hint: Is it a real image or
virtual image?)
