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.

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.
