The rate at which something occurs over a particular period of time. In the context of our fabrics, frequency describes the number of waves that pass a fixed point in a given amount of time.

 

 

For example if the time it takes for a wave to pass is ½ second, the frequency is 2 per second. If it takes 1/100 of an hour, the frequency is 100 per hour.

Frequency is measured in Hertz (Hz) and is named after the German physicist Heinrich Hertz.
Frequency is the measure of 1 wave cycle per secod (1 Hz).

Units of measure

1	Hz	=	1 cycle per second
1000	Hz	=	1 Kilohertz (kHz)
1000	kHz	=	1 Megahertz (MHz)
1000	MHz	=	1 Gigahertz (GHz)
1 GHz  =  1 Billion ( 1,000,000,000 Hz )
