SUMMARY
Planck's quantization of energy in electromagnetic waves effectively resolves the black body radiation problem by introducing the concept that energy is emitted in discrete packets called photons. This contrasts with the Rayleigh-Jeans law, which inaccurately predicted that energy would approach infinity as frequency increases. Planck's formula, E=nkh (where n represents discrete energy levels), demonstrates a peak in energy distribution, followed by a decline to zero, aligning with experimental observations. This quantization fundamentally changed the understanding of thermal radiation and laid the groundwork for quantum mechanics.
