Black Body Radiation | Ultraviolet Catastrophe | Black Body | Why did the classical model fail The classical model of physics failed to explain black body radiation due to a theoretical problem known as the ultraviolet catastrophe. This led Max Planck to develop the theory of quantum mechanics, which accurately predicted the observed radiation spectrum by introducing the concept of quantized energy. | Fadhel Mahdi

Quantum mechanics originated from Max Planck's attempt to solve the black body radiation problem—how ideal objects emit electromagnetic radiation. Classical physics predicted infinite energy at high frequencies (the "ultraviolet catastrophe"), but experiments showed radiation peaks and then falls. Planck resolved this by proposing that energy is quantized in discrete units of hf (frequency times Planck’s constant), introducing the concept of energy quantization and the foundation of quantum mech
