Frequency (symbol f), measured in hertz (symbol: Hz), is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as temporal frequency for clarity and to distinguish it from spatial frequency. Ordinary frequency is related to angular frequency (symbol ω, with SI unit radian per second) by ...
frequency, in physics, the number of waves that pass a fixed point in unit time; also, the number of cycles or vibrations undergone during one unit of time by a body in periodic motion. A body in periodic motion is said to have undergone one cycle or one vibration after passing through a series of events or positions and returning to its ...
LIGHT/SOUND/RADIO. [ U ] physics specialized. the number of times that a wave, especially a light, sound, or radio wave, is produced within a particular period, especially one second. frecuencia. the frequency of light. low frequency radiation. The human ear cannot hear very high-frequency sounds.
Frequency—number of waves passing by a specific point per second; Period—time it takes for one wave cycle to complete; In addition to amplitude, frequency, and period, their wavelength and wave velocity also characterize waves. The wavelength λ λ is the distance between adjacent identical parts of a wave, parallel to the direction of ...
Humans perceive the frequency of a sound as its pitch. Each musical note corresponds to a particular frequency. An infant's ear is able to perceive frequencies ranging from 20 Hz to 20 000 Hz; the average adult human can hear sounds between 20 Hz and 16 000 Hz.
frequency noun (LIGHT/SOUND/RADIO) [ U ] physics specialized. the number of times that a wave, especially a light, sound, or radio wave, is produced within a particular period, especially one second: the frequency of light. low frequency radiation.
