Question

Define the black body and white body radiation with examples

Answer 1

A black body is a theoretical object that absorbs 100% of the radiation that hits it. Therefore it reflects no radiation and appears perfectly black. ... 1.A simple example of a black body radiator is the furnace. If there is a small hole in the door of the furnace heat energy can enter from the outside.

White body: If all the incident radiation falling on the body are reflected , it is called a white body .

Answer 2

Black-body radiation has a characteristic, continuous frequency spectrum that depends only on the body's temperature, called the Planck spectrum or Planck's law.
