Fun with Oscilloscopes

Since we are now dealing with sinusoidally varying physical quantities, we can use them also to gnerate pretty patterns. To do this, we need an oscilloscope (or in this case: the software equivalent of one) for which we can vary the x- and y-deflection inputs separately. If one selects different sinusoidal inputs for the two axes and plays with the phases, one obtains pretty figures. Have fun experimenting!
