The length of the sea wave is 4 m. Determine how many vibrations an inflatable rubber boat makes on it in 20 seconds, if the wave propagation speed is 4 m / s.
the oscillation period is found by the formula T = t / N
from this formula, the number of oscillations can be found by the formula N = t / T, where t is the oscillation time, T is the oscillation period
t = 20 sec
the oscillation period can be found from the wavelength formula: L (lambda) = V * T
T = L / V
L = 4 m
V = 4 m / s
N = t * V / L
N = 20 * 4/4 = 20 vibrations
