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 periscope (Fig. P23.5) is useful for viewing objects that
cannot be seen directly. It can be used in submarines and
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 left–right reversed?
