A rectangular cross section rod is mounted vertically and the top is bent over at right angles. When the protruding end is struck it will describe Lissajous patterns. An elaborate apparatus made to reflect beams off mirrors - two oscillations in SHM and one that is the combination. An elaborate setup that uses three motors to produce a spot of light on a card that is the result of three mutually perpendicular SHM's. S-47 A slit in a lantern projector is driven in SHM and the resulting light beam is projected onto a white pencil mounted on a disc rotated by a motor in the perpendicular direction.
Most Lissajous figures illustrated in textbooks are wrong.
A Lissajous ellipse is drawn using the characteristic triangle method. Fully derived instructions.
