Quantum Physics-2024 Blackbody Radiation - ️️ - Radiation properties are independent of the material. The maximum of the distribution shifts to smaller wavelengths as the temperature is increased. The total power radiated increases with the temperature. One of the outstanding exceptions that classical physics could not explain, dubbed the "ultraviolet catastrophe" by Paul Ehrenfest. Blackbody - ️️ - Has the ideal property that it absorbs all the radiation falling on it and refle...
