Abstract
The interaction of electromagnetic waves with metal surface is analyzed in terms of electron waves and quasiparticles theory. Then a general relation between frequency and wavelength for excitations in condensed systems is obtained. It is shown how the work function for any metal depends on electron density and Fourier transform of potential due to a single electron. The effect of different factors on change of the work function value is considered.
