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

An object that is 4.0 cm tall is placed 15 cm in front of a concave mirror of
focal length 20 cm.
1) How far is the image from the mirror?
2) How tall is the image?

refractive index 2.0. In this liquid, its speed will be
a) 6.0 × 108 m/s
b) 3.0 × 108 m/s
c) 1.5 x 108 m/s
d) 0.75 × 108 m/s
