Asked by Tiara

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.
Answered by Henry
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.
