What is an example of frequency

'Frequency' is a word that often confuses some people ... for no good reason.

It just means "frequent-ness" or "often-ness" ... how often something happens.

The SI unit of frequency is the Hertz (Hz). Hz means 'per second'.

So " 13 Hz " means 13 per second.

Here are examples of frequency:

- - 780 kilohertz (on your AM radio dial)

- - 98.7 Megahertz (on your FM dial)

- - 5.8 Gigahertz

- - twice a day

- - three per week

- - every 6 months

For example 75 Hertz means that there are 75 wave tops per second in for example a radio signal.
