The fisherman noticed that in 20 seconds the float made 30 oscillations on waves, and the distance between adjacent wave humps was 1.5 m. What is the speed of wave propagation.
t = 20 s – oscillation time
N = 30 count – the number of oscillations
L = 1.5 m – wavelength
we write down the formula for finding the wavelength and express the velocity from this formula:
L = V * T, where T is the oscillation period
V = L / T
oscillation period – the time during which one complete oscillation occurs:
T = t / N
T = 20/30 = 2/3 s
V = 1.5 / 2/3 = 1.5 * 3/2 = 2.25 m / s
