Web5. The physical meaning is the length of electron trajectory along which this electron gains phase factor comparable with 2 π from the magnetic field. Normally, it is rather large. When is is as small as lattice constant, it means that the magnetic field is comparable with electric field in the atom which is rather rare situation. Share. WebIn addition to amplitude, frequency, and period, their wavelength and wave velocity also characterize waves. The wavelength λ is the distance between adjacent identical parts of a wave, parallel to the direction of propagation. The wave velocity v w is the speed at which the disturbance moves.
