Definition of oscillation. 1  1 : the action or state of oscillating stays can be effectively used to prevent oscillations in new bridges â D. B. Steinman. 2  2 : variation, fluctuation famines due to excessive storminess and violent oscillations of rain and drought, heat and cold â Ellsworth Huntington.
frequency: The number of oscillations (vibrations) in one second. Frequency is measured in Hertz (Hz), which is the same as oscillations per second or cycles per second.. For example, the alternating current in a wall outlet in the U.S. and Canada is 60Hz.requency (wave motion). The number of times which sound pressure, electrical intensity, or other quantities specifying a wave vary from their equilibrium value through a complete cycle in unit time. The most common unit of frequency is the hertz (Hz), which is equal to 1 cycle per second.
