Rotating wave approximation — The rotating wave approximation is an approximation used in atom optics and magnetic resonance. In this approximation, terms in a Hamiltonian which oscillate rapidly are neglected. This is a valid approximation when the applied electromagnetic… … Wikipedia

Utility frequency — The waveform of 230 volt, 50 Hz compared with 110 V, 60 Hz. The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the frequency at which alternating current (ac, also AC) is transmitted from a… … Wikipedia
Angular frequency — Not to be confused with angular velocity. Angular frequency ω (in radians per second), is larger than frequency ν (in cycles per second, also called Hz), by a factor of 2π … Wikipedia
Negative frequency — The concept of negative and positive frequency can be as simple as a wheel rotating one way or the other way.[citation needed] A signed value of frequency indicates both the rate and direction of rotation.[citation needed] The rate is expressed… … Wikipedia
