Imagine that spherical mirrors were not known to human beings. Guess the consequences. (A52)

New inventions are discovered everyday in order to make life easy & comfortable while others are invented in order to fulfill our day to day needs. A world without spherical mirrors would be a world in dark. If spherical mirrors are not known to humans then the consequences are:

a. Convex mirrors are used in as the rear side view mirror so as to get a wider view of the vehicles coming behind. If plane mirrors are used instead of convex mirrors, we would not be able to get a wider view.

b. Plane mirror cannot magnify the image. Convex mirrors has the ability to magnify the image of the object. In the absence of it, magnifying glass cannot be made.

c. We will not be able to explore our galaxy if spherical mirrors are not discovered as telescopes use lenses which are made with the help of these mirrors.

d. Surveillance mirrors used in many showrooms to keep an eye on people are made up of spherical mirror. Thus, this application would not be available if these mirrors are not known.

e. Solar cookers use concave mirrors to concentrate the sun rays on a point. If concave mirrors were not known then we would not be able to use this conventional source of energy.
