The boat sways in the sea on waves propagating at a speed of 2 m / s. The distance between the nearest wave crests is 6 m. What is the frequency of the waves hitting the boat’s hull?
λ = V * T, where
λ is the wavelength (in our case, this is the distance between the wave crests);
V is the speed with which the waves propagate;
T is the oscillation period.
We find the oscillation period by the formula: T = λ / V = 6/2 = 3 s.
Oscillation frequency:
ν = 1 / T = 1/3 = 0.33 Hz.
