A periscope is useful for viewing objects that cannot be seen directly. It can be used in submarine sand when watching golf matches or parades from behind a crowd of people. Suppose the object is a distance p1 from the upper mirror and the centers of the two flat mirrors are separated by a distance h.(a) What is the distance of the final image from the lower mirror?(b) Is the final image real or virtual?(c) Is it upright or inverted?(d) What is its magnification?(e) Does it appear to be leftright reversed?
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.
