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.
A photographer took this image of himself in a converging mirror. Give some thought to what you are seeing here: One of the hands is his left hand; the other is the image of his left hand. Given the relative sizes and positions
of his hand and the image of his hand, how far from the mirror did he place
his hand to take this photo? Express your answer in terms of f, the mirror’s
focal length.
