. Define.(i) Reflection (ii) Mirror or Reflector

Best Answer

The phenomenon of turning back of light, when incident on the boundary of two media (such as air and glass), is called reflection. Surfaces that cause reflection are known as mirrors or reflectors. 

A mirror is a surface which doesn’t allow light to pass through it. Whatever light is incident on it is sent back into the medium from which it came from. A mirror is typically obtained by polishing one side of a glass surface and silvering the other side. Light interacts with the polished face of the mirror
