You dip your finger into a pan of water twice each second, producing waves with crests that are separated by 0.15 m. Determine the frequency, period, and speed of these water waves.

  1. frequency= 2waves/sec

    wavelength= .15m

    speed= 2hz*.15m= .30m/sec

  2. Twice a second is frequency = 2 Hz
    The period is therefore 1/2 = 0.5 seconds
    In .5 seconds the wave goes .15 meters so its speed is
    .15/.5 = .30 m/s
