Frequency, interference & resonance — the shared physics behind transverse, longitudinal and sound waves.
Compare side-to-side rope-wave motion against slinky-style compression and rarefaction driven by the same source.
Adjust frequency and speed and watch wavelength update live through the wave equation v = fλ.
See how wave energy and power scale with the square of amplitude on a live energy bar and pulsing power indicator.
Overlay two waves and watch constructive and destructive interference build the summed waveform in real time.
Drive a string fixed at both ends and find the harmonic modes where nodes and antinodes lock into place.
Drive a damped oscillator near its natural frequency and watch amplitude build sharply on a live response curve.
Move a wave source past a stationary observer and see wavefronts compress and stretch, shifting observed frequency.
Combine two close frequencies and watch the amplitude envelope pulse at the beat frequency.
Watch air molecules bunch into compressions and spread into rarefactions as a pressure wave propagates.
Send a pulse toward a boundary and compare fixed-end, free-end and medium-change reflection and transmission.
