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

A student who is 1.59 m tall walks into a drugstore and stands 4.83 m in front of a convex mirror. The image of the student in the mirror is 6.16 cm tall. What is the focal
length of the mirror in millimeters? (State answer with correct sign as an integer. Do not include unit in answer.)
