Planck statement - Study guides, Class notes & Summaries

Quantum Physics Study Guide There have been two models of light. What are they and who first supported each? Particle: Newton and wave: Huygens (1600s) What determines the color with which a body glows? temperature What is Planck's equation? E=hf What does Planck's equation mean? Energy comes in discrete packets. Energy of a photon is proportional to its frequency. What does Planck's equation explain? Blackbody radiation problem and the photoelectric effect What is Planc...
