There are 2 complete waves shown in the diagram. The wavelength is the length of one wave, 40 cm. The amplitude is the height of the wave, 10 cm. A displacement-time graph shows how the ...

Be careful with this quantity - the centre line is not always given in a diagram. Amplitude is measured in metres (\(m\)). The greater the amplitude of a wave then the more energy it is carrying.

Amplitude modulation (AM) is also widely used to alter a carrier wave to transmit data. For example, in AM radio, the voltage (amplitude) of a carrier with a fixed center frequency (the station's ...

Most scales are based on the amplitude of seismic waves recorded on seismometers ... To give you an idea how these numbers can add up, think of it in terms of the energy released by explosives: a ...
