*A beam of light reflected from the mirror, was allowed to trace patterns which depended on the frequencies of the sounds – in a setup similar to projectors used in today's laser light shows.

*Lissajous figure is the intersection of two sinusoidal curves, the axes of which are at right angles to each other.
*Lissajous figure is the intersection of two sinusoidal curves, the axes of which are at right angles to each other.
*Mathematically, this translates to a Complex harmonic function:The appearance of a figure is highly sensitive to a/b, the ratio of a and b.
*Mathematically, this translates to a Complex harmonic function:
<math>x=A Sin(at+\delta)</math>,<math>y=B Sin(bt)</math>
*The appearance of a figure is highly sensitive to a/b, the ratio of a and b.
*According to the ratio value, the shapes of the figures change in interesting ways.
*According to the ratio value, the shapes of the figures change in interesting ways.
*For a a/b ratio=1, the figure is an ellipse.
*For a a/b ratio=1, the figure is an ellipse.
