WebThe primary law governing blackbody radiation is the Planck Radiation Law, which governs the intensity of radiation emitted by unit surface area into a fixed direction from the blackbody as a function of wavelength for a fixed temperature. The Planck law is represented by the shape of curves in the figure to the right. WebA black body in thermal equilibrium (that is, at a constant temperature) emits electromagnetic black-body radiation. The radiation is emitted according to Planck's law, meaning that it has a spectrum that is determined by the temperature alone (see figure at right), not by the body's shape or composition. An ideal black body in thermal ...

Anyone who's ever used a toaster will have noticed that when the heating elements get hot, they start to emit light. Initially, when they're warming up, the colour is dark red. When they get hotter, they get brighter, and the colour is more orange. Similarly, next time you're stargazing, take a look at Orion. harper hospital patient information
