In ancient, times, however, theories about sound ranged from the idea of streams of atoms, proposed by. It is a time-independent wave equation, also known as the frequency-domain wave equation, that is used to calculate the motion of seismic waves through the Earth. Equations (2), (3), and (4) are different forms of the plane-progressive wave equation, for a wave that moves from left to right so the vibration of particle P lags on that at O. For spherical waves, you have to multiply the amplitude by 1/r. The solution of this one-dimensional wave equation is uniquely determined by the initial conditions given below: u (x, 0) = f (x) .
