History of Spherical Mirrors in Human Civilization
A spherical mirror possesses either a concave or a convex surface. It is a form of a true sphere. There are two different types of spherical mirrors, namely concave and convex. Shaving mirrors and makeup mirrors are examples of concave mirrors.
The use of these mirrors is quite common as they are used in everyday life. They help in enlarging the objects kept near them. Below, we have covered the history of spherical mirrors in brief:
