Max Planck was awarded the Nobel Prize in Physics in 1918 in recognition of his discovery of ?
Show answer Hide answer
Answer: B. energy quanta
Explanation
Max Planck discovered that energy is emitted in discrete packets called quanta. This revolutionary concept launched the entire field of quantum mechanics. He was awarded the 1918 Nobel Prize for discovering energy quanta. Blackbody radiation problems prompted Planck to introduce his quantum hypothesis. Planck constant relates the energy of a photon to its frequency. Classical physics failed to explain atomic phenomena before quantum theory.
Quantum mechanics underpins modern electronics, lasers, and semiconductor technology. Physicists use energy quanta calculations to study subatomic particle behaviors. Planck work changed humanity fundamental understanding of light and matter. J.J. Thomson discovered the electron rather than formulating energy quanta. Photons represent individual light particles described by later quantum theories. Positrons are antimatter particles discovered later by Carl Anderson.
