Black body

In physics, a black body is an object that absorbs all electromagnetic radiation that falls onto it.

See also:

No radiation passes through it and none is reflected, yet in classical physics, it can theoretically radiate any possible wavelength of energy.

Despite the name, black bodies are not actually black as they radiate energy as well.

The amount and type of electromagnetic radiation they emit is directly related to their temperature.
