We presesent an exact generalization of the Foldy-Lax formula for the self-energy of a wave propagating in a disordered system of identical spherical scatterers. The Foldy-Lax formula yields an expression for the self-energy valid to first order in the density of scatterers. Our exact formula ...
Since light is a wave phenomenon, you can express Planck's equation in terms of wavelength, represented by the Greek letter lambda (λ), because for any wave, the velocity of transmission is equal to its frequency times its wavelength. Since the speed of light is a constant, denoted...
Current interest in laser-driven ion accelerators, as a radically different, compact alternative to RF accelerators, stems from remarkable properties such as large particle flux, short pulse duration and exceptional beam emittance1. However, the large angular and spectral spread of the ion beams which...
c = speed of light = 3 x 108m/sec λ = wavelength ν = frequency Rearrange the equation to solve for frequency: ν = c/λ Read More Calculate Photon Energy from Frequency By Todd Helmenstine Next, replace frequency in the first equation with c/λ to get a formula you can use: ...
Excitation, in physics, the addition of a discrete amount of energy (called excitation energy) to a system—such as an atomic nucleus, an atom, or a molecule—that results in its alteration, ordinarily from the condition of lowest energy (ground state) t
. The energy from shock waves includes 0.1 cal cm−2yr−1from meteorites and meteors and 1 cal cm−2yr−1from the shock or pressure wave of a lightning bolt. See A. Bar-Nun et al. [Science (1970) 168, 470–473]. The figures for ultraviolet light are from H.E. Hinteregger...
The fine structure is produced by the electron wave originating from an inner shell that is partially back-reflected by the surrounding atoms, which leads to a modulation of the excitation probability of inner-shell electrons. This fine structure can therefore provide information not only on the ch...
