Magnitude of a sound
WebWhile not negligible, this is not a strong dependence. At 0 °C, the speed of sound is 331 m/s, whereas at 20.0 °C, it is 343 m/s, less than a 4 % increase. Figure 17.6 shows how a bat uses the speed of sound to sense distances. Figure 17.6 A bat uses sound echoes to find its way about and to catch prey.

WebAmplitude. The amplitude of a periodic variable is a measure of its change in a single period (such as time or spatial period ). The amplitude of a non-periodic signal is its magnitude compared with a reference value. There are various definitions of amplitude (see below), which are all functions of the magnitude of the differences between the ...
