Frequency refers to how many waves are made per time interval. This is usually described as how many waves are made per second, or as cycles per second.

The following interactive diagram lets you adjust the frequency of the wave train.

Java

If ten waves are made per second, then the frequency is said to be ten cycles per second, written as 10 cps.

Usually, we use the unit Hertz to state frequency. A frequency of 10 cps is noted as a frequency of 10 Hertz. So, one cycle per second is one Hertz, as in:

1 cps = 1 Hertz

The unit Hertz is abbreviated this way:

1 Hertz = 1 Hz
