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 ...

Researchers from Beihang University in China have created a spintronic THz emitter with a microscale stripe pattern that ...

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 ...

1. The amplitude of a wave is the maximum displacement of a point of a wave from its rest position. This is exactly half the distance between a crest and trough. The distance between a crest and ...
