About Jules Antoine Lissajous
- Jules Antoine Lissajous (French pronunciation: ?[?yl ?~twan lisa?u]) (March 4, 1822 in Versailles – June 24, 1880 in Plombières-les-Dijon) was a French physicist, after whom Lissajous figures are named.
- Among other innovations, Lissajous invented the Lissajous apparatus, a device that creates the figures that bear his name.
- In it, a beam of light is bounced off a mirror attached to a vibrating tuning fork, and then reflected off a second mirror attached to a perpendicularly oriented vibrating tuning fork (usually of a different pitch, creating a specific harmonic interval), onto a wall, resulting in a Lissajous figure.
- This led to the invention of other apparatus such as the harmonograph.
