Five pulses are generated every 0.094 s in a tank of water. What is the speed of propagation of the wave if the wavelength of the surface wave is 1.14 cm?

can you break it down please.

  • Physics -

    F = 5 / 0.094 = 53.2 Pulses/s =
    frequency of pulses.
    T = 1/F = 1/53.2

    L = VT,
    V = L/T = LF,
    V = 1.14cm * 53.2pulses/s = 60.6cm/s.

    L = wavelength in cm.
    F = frequency in pulses / s.
    T = Period of frequency.
