Waves — v = fλ

v=f×λ=2×2=4m/sv = f \times \lambda = 2 \times 2 = 4\,\text{m/s}
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)
