Solution

  1. A mirror that has the shape of a piece cut out of a spherical surface is called a spherical mirror.
  2. It is of two types:
  • Concave mirror: These are the spherical mirror that is curved inward and the image obtained from these mirrors depends on the object’s placement.
  • Convex mirror : These are the spherical mirror that is curved outward and the image obtained is virtual, diminished and erect for a real object.
  1. The first spherical mirrors in human civilization used were water collected in a primitive vessel or utensil. The earliest manufactured mirrors used by humans were pieces of polished stone.
  2. The obsidian mirrors were found in Anatolia (now popularly known as Turkey). Mirrors of polished copper were crafted early in the Mesopotamian civilization from 4000 BC and in ancient Egypt from around 3000 BC.
