WebMar 18, 2024 · Quantizing Electrons in the Radiator. In 1900, the German physicist Max Planck (1858–1947) explained the ultraviolet catastrophe by proposing that the energy of electromagnetic waves is quantized rather than continuous. This means that for each temperature, there is a maximum intensity of radiation that is emitted in a blackbody … WebPlanck found the formula he had struck two months earlier. He added further proof of the value of his formula by using it to test the constant h (his value was 6.55 × 10-27 erg-second, close to the modern value of 6.626 × 10-27 erg-second). Therefore, he derived the formula to calculate the energy of the radiation.
