WebMay 20, 2024 · The Wavelength of a Black Body calculator compute the wavelength of the strongest emissions from a black body based on its temperature. Its wavelengths are more than twenty times that of the Sun, tabulated in the third column in micrometers (thousands of nanometers). That is, only 1% of the Sun's radiation is at wavelengths shorter than 296 nm, and only 1% at longer than 3728 nm. Expressed in micrometers this puts 98% of the Sun's radiation in … See more 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 … See more Planck's law can be encountered in several forms depending on the conventions and preferences of different scientific fields.
