[list][*]The simulation represents a transverse wave traveling to the right. [/*][*]Use the sliders to set the amplitude and wavelength of the wave.[/*][*]The distance of point Q along the wave can be set using the distance[br] slider. The two vectors on the left show the displacement of the two [br]points P and Q. The phase difference gives the phase of Q relative to P.[/*][*]Click the play/pause button (bottom left) to play or pause the animation. You can also drag the [i]t[/i] slider to show the wave at a particular time (note that [i]t[/i] is given as a fraction of a [b]period[/b] of the wave).[/*][/list]
