As waves travel, they set up patterns of disturbance. The amplitude of a wave is its maximum disturbance from rest (its undisturbed position). Key fact It is important to note that the amplitude ...

You need to know about these quantities used in waves - what they mean, the symbols used for them and the units used to measure them. The amplitude (\(a\)) of a wave is the distance from the ...

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 ...
