About This Product
Turning the crank moves each sphere in simple harmonic motion, a little behind its neighbour, so a sine wave appears to run along the row while each sphere only goes up and down. Because the 24 steps of 15° add up to one full turn, one complete wavelength is shown, and students can point out crests, troughs, amplitude and phase, and see how cranking faster raises the frequency.
Frequently Asked Questions
Why are the cams of the Wave Motion Apparatus (24 Pulleys) STEM Lab offset by 15°?
Each cam is 15° ahead of the next, so the 24 cams together cover one full cycle and the spheres trace one complete wavelength.
