... In an analysis relating Bohr's theory to the de Broglie wavelength of electrons, when an electron moves from the n = 1 level to the n = 3 level, the circumference of its orbit becomes 9 times greater. This occurs because (a) there are 3 times as many wavelengths in the new orbit, (b) there are 3 tim ...

... Calculating the energy of a quantum or photon • E=h • Energy of a photon = Planck’s constant x frequency • Planck’s constant = 6.626 x 10-34 J-s • Every object gets its color by reflecting a certain portion of incident light. The color is determined by the wavelength of the reflected photons, thus ...

... How does f(x0) relate to averages of f(x) at nearby positions? Therefore fε(0) = f(0) + (ε/d) ∇2 f(0) + … The Laplacian provides a measure of how the spherical average of a function changes as the radius increases. Quantum mechanics is a mystery, but in so far as a classical interaction V(x) at a ...

... The plot of hν versus mass attenuation shows some sharp discontinuities where hν equals the binding energy of particular electronic shells. These discontinuities, called absorption edges, are caused because for a particular shell, the electrons cannot undergo the photoelectric effect without energy ...

Quantum electrodynamics
In particle physics, quantum electrodynamics (QED) is the relativistic quantum field theory of electrodynamics. In essence, it describes how light and matter interact and is the first theory where full agreement between quantum mechanics and special relativity is achieved. QED mathematically describes all phenomena involving electrically charged particles interacting by means of exchange of photons and represents the quantum counterpart of classical electromagnetism giving a complete account of matter and light interaction.In technical terms, QED can be described as a perturbation theory of the electromagnetic quantum vacuum. Richard Feynman called it ""the jewel of physics"" for its extremely accurate predictions of quantities like the anomalous magnetic moment of the electron and the Lamb shift of the energy levels of hydrogen.
