The important breakthrough in theoretical physics that was first suggested by Planck to explain the shape of the spectrum of a hot body was the A) discovery of the formula F = $\sigma$T⁴, which can be used to calculate the total energy flux emitted by the hot body over all wavelengths. B) idea that light traveled at a constant speed, whatever the speed of the source. C) idea that light is a form of electromagnetic energy transmitted at a constant speed and that there is a continuous spectrum of electromagnetic waves from gamma rays to radio waves. D) concept that electromagnetic energy was emitted in small packets, or quanta.

Question

Quizplus · Accepted Answer

Max Planck introduced the concept of quantization of energy to explain blackbody radiation, suggesting that electromagnetic energy could only be emitted or absorbed in discrete amounts called quanta. This was a fundamental breakthrough in theoretical physics, leading to the development of quantum mechanics.
