Study radiation effect with this tool. Black Body is a small, simple, easy to use application specially designed to display this radiation effect.
The user can take several snapshots of the radiation spectrum in order to compare the effect at different temperatures.

The emission of radiation of a non-reflecting ideal black surface is defined by Planck's radiation law. It states that the emitted radiation power increases with increasing temperature and that the maximum of the radiated spectrum is shifted towards shorter wavelengths with rising temperature. The location (wavelength) of the maximum is described by Wien's displacement law which states that there is an inverse relationship between the temperature of a blackbody and the wavelength of the peak emission.
