The distance between adjacent crests of sea waves is 4 m, and before the period of the boat oscillation on waves of 1.5 s, determine the speed of the wave
λ = 4 m.
T = 1.5 s.
V -?
The wavelength λ is the smallest distance between points that oscillate in the same phase. Wavelength λ is the distance between adjacent peaks or troughs in the wave.
The speed of propagation of the sea wave V is determined by the formula: V = λ * v, where λ is the wavelength, v is the frequency of the wave.
We express the frequency of the wave v by the formula: v = 1 / T, where T is the oscillation period.
The formula for determining the wave speed will take the form: V = λ / T.
V = 4 m / 1.5 s = 2.7 m / s.
Answer: the speed of the sea wave is V = 2.7 m / s.
