Here's a breakdown:
* Hertz (Hz) is the unit of measurement for frequency.
* Frequency is the number of occurrences of a repeating event per unit of time.
* Cycle refers to one complete repetition of the event.
Therefore, 1 Hz means that something is happening once every second.
Examples:
* A pendulum swinging back and forth once every second has a frequency of 1 Hz.
* A light wave vibrating 1,000,000 times per second has a frequency of 1 MHz (1 megahertz).
* A sound wave oscillating 440 times per second has a frequency of 440 Hz.
Time is not directly measured in Hertz. To understand how long 1 Hz lasts, imagine a clock ticking once per second. The time it takes for one tick is one second.
