Waves — v = fλ
Wave speed4.0 m/s
Period0.50 s
- Get the wave speed to at least 6 m/s
- Switch to a LONGITUDINAL wave and watch the compressions travel
- Tune frequency and wavelength so the wave speed is exactly 20 m/s
- Bring the period below 0.3 s — how high must the frequency climb?
- Make a wave that oscillates FAST (frequency ≥ 4 Hz) but travels SLOWLY (speed ≤ 3 m/s)
