Das lag wohl vor allem daran, dass Fox News Joe Biden früh zum Sieger in Arizona erklärte. Part II. One simple way to see it is to note that the clock on a moving source runs slow by a factor of γ, so that it appears (to a stationary observer) to take the source a bit longer to create … Video von ausgezeichneter Qualität. In general, Doppler broadening is the broadening of spectral lines due to the Doppler effect caused by a distribution of kinetic energies of molecules or atoms.
