Polarization — ( Brit. polarisation) is a property of waves that describes the orientation of their oscillations. For transverse waves, it describes the orientation of the oscillations in the plane perpendicular to the wave s direction of travel. Longitudinal… … Wikipedia
Vacuum energy — is an underlying background energy that exists in space even when devoid of matter (known as free space). The vacuum energy is deduced from the concept of virtual particles, which is itself derived from the energy time uncertainty principle. Its… … Wikipedia
Vacuum permittivity — This article is about the electric constant. For the analogous magnetic constant, see vacuum permeability. For the ordinal in mathematics ε0, see epsilon naught. The physical constant ε0, commonly called the vacuum permittivity, permittivity of… … Wikipedia
Vacuum Rabi oscillation — A vacuum Rabi oscillation is a damped oscillation of an initially excited atom coupled to an electromagnetic resonator or cavity in which the atom alternately emits photon(s) into a single mode electromagnetic cavity and reabsorbs them. The atom… … Wikipedia
