Problems on wave equation
http://www.mathtube.org/sites/default/files/lecture-notes/Lamoureux_Michael.pdf WebbMany wave problems feature sinusoidal oscillations in time and space. For example, the original PDE problem (1) - (5) allows an exact solution ue(x, t) = Asin(π Lx)cos(π Lct). This ue fulfills the PDE with f = 0, boundary conditions ue(0, t) = ue(L, 0) = 0, as well as initial conditions I(x) = Asin(π Lx) and V = 0 .

WebbThe wave equation is linear: The principle of “Superposition” holds. This has important consequences for light waves. It means that light beams can pass through each other without altering each other. It also means that waves can constructively or destructively interfere. If f 1 (x,t) and f 2 (x,t) are solutions to the wave equation, then ... WebbTwo points A and B are on the rope and are 90 cm apart from one another. On the rope propagates the transverse waves, so that point A is at the top of the wave, point B at the bottom of the wave, and between them, there are two crests and two troughs. If the wave period is 0.3 seconds, then the wave propagation is… A. 10.8 cm/s. B. 18.0 cm/s
Webbextremes. Here, when we are dealing with wave equations, we will be considering both the cases homogeneous wave equation and non- homogeneous wave equation. If we define (initialize) the independent variable at the lower boundary of the domain, we can often term homogeneous wave equations as initial boundary value problems.
