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 displacement of one point on the wave varies over time.

Amplitude – the distance from ... the wave to the same point on the next cycle of the wave. Figure caption, This displacement-distance graph is how you would measure a wavelength of a wave ...

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 ...

Velocity (and therefore pressure) is greatest mid-way between the maximum displacement of the vibrating body, and we can graph the resulting relationship between amplitude and sound pressure in the ...
