Frequency is the number of occurrences of a repeating event per unit of time, usually measured in hertz (Hz). Learn how frequency relates to period, angular frequency, spatial frequency, and wave phenomena, and how to measure frequency using different methods.
Learn the definitions, formulas and examples of frequency, time period and angular frequency of sinusoidal waves. Find out how they are related and how to measure them in SI units.
- A wave is a disturbance that travels through a medium from one location to another location.
- We define the frequency of a sinusoidal wave as the number of complete oscillations made by any element of the wave per unit of time.
- The time period of oscillation of a wave is defined as the time taken by any string element to complete an oscillation.
- The angular frequency refers to the angular displacement of any wave element per unit of time or the rate of change of the waveform phase.
5 days ago · 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.
