Harmonic motion projector
Laser projector for harmonic oscillations: a rotating hexagonal mirror projects a sinusoidal trace onto a screen.
Mechanical vibration demonstration device consisting of 4 components: base with control panel, harmonic vibration generator, laser source and hexagonal rotating mirror. Designed for 4 demonstrations: projection of harmonic oscillations producing a sine and cosine wave on the screen, dependence of the wave height on the amplitude of oscillations of the mirror plate, changes in the pattern as the frequency and mirror rotation speed are adjusted, as well as sinusoidal motion as a consequence of the linear restoring force. Makes an abstract sine wave visible on the screen in real time.
- 1.Base with control panel - 1 pc.
