Quantum Physics-2024 Blackbody Radiation - ️️ - Radiation properties are independent of the material. The maximum of the distribution shifts to smaller wavelengths as the temperature is increased. The total power radiated increases with the temperature. One of the outstanding exceptions that classical physics could not explain, dubbed the "ultraviolet catastrophe" by Paul Ehrenfest. Blackbody - ️️ - Has the ideal property that it absorbs all the radiation falling on it and refle...

ATOMIC STRUCTURE Earlier in this course, we explored a very elementary view of atomic structure. We learned about protons, neutrons, and electrons (the three elementary particles that comprise an atom) and their properties. In this module, we will study these particles in detail and learn how their presence and arrangement determines the properties of all matter. The Electron During the 1800s, a number of scientists, including Sir Humphrey Davy, Michael Faraday, R. A. Milligan, G. J. Sto...
