Amazing and simple plate vibration with an AC oscillator signal generator.
The large motion of the plate is where "resonance" occurs and the semolina is moved more and then moves away this is an antinode. The "nodes" are where the waveform is stationary and a point of inflection. You can see how different standing waves fit onto the plate to produce the pattern, you could work out the speed of sound of travel through the material using this setup and a ruler if you know the frequency, which I did!
