A light bulb is 3.0 m from a wall. You are to use a mirror to project an image of the bulb on the wall, with the image 3.25 times the size of the object. a) Without calculations, what type of mirror is needed and why? b) Where will the image be formed? c) What is the focal length of the mirror?
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.
