We have frequently used the following representative waveform equation in order to describe several kinds of waves (waves on a string, sound waves in gases and solids, etc.) where 0 is the amplitude of the sinusoidal displacement wave. The amplitude 0 is a constant that is specified by the source of the waves which may be a speaker for sound waves in air. For a wave equation, we observe the same amplitude 0 everywhere along the wave that is propagating in a lossless media. Such waves are called one-dimensional or plane waves. The terminology of a plane wave results from the fact that all points transverse to the direction of propagation reside in a plane. |
