What unit is frequency depicted in?

Frequency is depicted in Hertz (Hz), which is the standard unit used to measure the number of cycles per second of a periodic phenomenon. When a signal oscillates, such as in radio waves or sound waves, the frequency indicates how many cycles occur in one second. This unit is fundamental in various fields, including telecommunications, audio engineering, and electronics, as it determines the pitch of sounds and the bandwidth of signals.

Other choices represent different electrical concepts: Amperes is the unit of electrical current, Ohms measures electrical resistance, and Volts quantify electric potential or electromotive force. These units are important in their own right but do not relate to the measurement of frequency. Hertz is specifically tailored to quantify how often an event occurs in a designated period, making it the appropriate choice for measuring frequency.
