What is the unit of frequency?

The unit of frequency is Hertz, which is a measure of how many cycles of a periodic wave occur in one second. Frequency is a fundamental concept in various fields, including physics, engineering, and communications, particularly in radio. When a radio wave oscillates, it completes a full cycle in a specific time frame, and Hertz quantifies this activity. For instance, a frequency of 1 Hertz means that one cycle occurs per second.

Other units mentioned, such as Henry, Farad, and Tesla, represent different physical concepts. The Henry is the unit of inductance, the Farad is a measure of capacitance, and the Tesla is used for magnetic flux density. While these units are important in their respective areas, they do not relate to the measurement of frequency, which is exclusively defined by Hertz.
