Find a wave function, g(x,t), that will produce a standing wave with
a node at x=0, (i.e., at the center.)
What wave function, g(x,t), will produce a beat wave with a beat frequency
of 0.2 Hz.
Traveling waves need not be sinusoidal. Find a wave function, g(x,t),
that interferes destructively with the incoming wave, f(x,t), at the point
