Blackbody spectrum equation
WebA blackbody is a body that absorbs all wavelengths of light. No light is reflected and therefore, at low temperature, it appears black. Emission from a blackbody is temperature dependent and at high temperature, a blackbody will emit a spectrum of photon energies that span the visible range, and therefore it will appear white.

WebFor a blackbody radiator, the temperature can be found from the wavelength at which the radiation curve peaks. Discussion. If the temperature is = C = K, then the wavelength at which the radiation curve peaks is: λ peak = x10^ m = nm = microns. This wavelength corresponds to quantum energy. hν = x 10^ eV. Region of. spectrum. WebIn 1900, the British physicist Lord Rayleigh derived the λ−4 dependence of the Rayleigh–Jeans law based on classical physical arguments, relying upon the equipartition theorem. This law predicted an energy output that diverges towards infinity as wavelength approaches zero (as frequency tends to infinity). Measurements of the spectral ...
