This period is the reciprocal of the frequency. This is written as: T = 1/f. where T is the period and f is the frequency. The SI unit for frequency is the hertz (Hz), which is equal to 1/s, or once per second. Frequency is encountered many times in physics. A few highly important instances are listed here. All waves in physics are said to have frequency.
Watt is the unit of power. Hertz (Hz) is a unit of frequency, defined as the number of complete cycles of a periodic signal that take place in one second. Ampere (SI unit symbol: A), often shortened to amp, is the SI unit of electric current (dimension symbol: I) and is one of the seven SI base units.
