Frequency is how often something happens.

A frequency diagram.
To measure sounds frequency you have to do a sound test.
you can determine it by the wavelenght and the period of the wave and the frequencey
The hertz (Hz) is commonly used. Its dimensions are 1/second.
Frequency = (speed)/(wavelength) = 10/20 = 1/2
The Doppler effect is a change of the frequencey of a wave, due to relative movement between source and observer.
Radio waves they are low frequencey; and it is what is emitted at very low temperatures
Rechargable battery life willd epend on the device in which they are used and the frequencey in which they are charged.
Visible light has lower frequency / longer wavelength than x-rays.
