The boat sways in the sea on waves propagating at a speed of 2m / s. The distance between the nearest waves is 6m. What is the frequency of the waves.
V = 2 m / s.
λ = 6 m.
v -?
The distance between the two nearest wave crests is called the wavelength λ = 6 m.
The speed of propagation of the wave V is determined by the formula: V =
λ * v, where λ is the wavelength, v is the wave frequency.
v = V / λ.
v = 2 m / s / 6 m = 1/3 Hz.
Answer: the frequency of impacts of waves on the sea is v = 1/3 Hz.
