Click and drag to adjust the current wave displacement at different points along the curve. The light grey lines are different terms of the Fourier series at the current moment — the linear combination of these gives the black line.

Try creating standing waves, for instance picking out a single Fourier mode.

Try creating small impulses and see how they reflect off of the boundaries.

Try creating the shape you would imagine a string would be when it is about to be plucked.
