Harmonic Oscillator Laser: this rave laser pointer reflects the beam off of a small mirror mounted on a spring, projecting elliptical and higher level Lissajous figures as the spring oscillates along two axes. Fun that complex patterns can arise from such a simple mechanism with this vintage laser toy. ➡️ Follow the link in my profile for info on where to get many of the amazing items featured here on @physicsfun #Lissajous #laser #harmonic #oscillator #harmonicoscillator #ellipse #physicstoy #p
