Blackbody radiation and planck's hypothesis

In physics, Planck's law describes the spectral density of electromagnetic radiation emitted by a black body in thermal equilibrium at a given temperature T, when there is no net flow of matter or energy between the body and its environment. At the end of the 19th century, physicists were unable to explain why the observed spectrum of black-body radiation, which by then had been accurately measured, diverged significantly at hig… WebDec 30, 2024 · Blackbody Radiation.

The black body is also a perfect light bulb over all wavelengths, but there is a single wavelength where radiation is very strong.

WebIn an attempt to determine the cause of the probability factor, Max Planck constructed a new theory. This theory, which created the branch of physics called quantum mechanics, speculated that the energy radiated by the blackbody could exist only in specific numerical, or quantum, states.
