A wave propagates on the surface of the lake at a speed of 3 m / s. What is the vibration frequency of the boat if the wavelength is 3m?
V = 3 m / s
λ = 3 m
f -?
The speed of propagation of mechanical waves is determined by the formula V = λ * f, where λ is the wavelength, f is the vibration frequency. Let us express the frequency f = V / λ. f = 3 m / s / 3 m = 1 Hz. The wave on the surface will have a frequency of 1 Hz, which means that the boat will vibrate at a frequency of 1 Hz.
Answer: the frequency of vibration of the boat is 1 Hz.
