The beacon oscillates in the sea oscillates on waves with a period of 2 seconds. The speed of the sea waves is 1m / s, which is equal to the wavelength.
T = 2 s.
V = 1 m / s.
λ -?
The wavelength λ is the distance between the nearest crests or troughs of the wave.
The wavelength λ is determined by the formula: λ = V / v, where V is the wave propagation speed, v is the wave frequency.
The oscillation frequency v is related to the oscillation period T by the formula: v = 1 / T.
The formula for determining the wavelength will take the form: λ = V * T.
λ = 1 m / s * 2 s = 2 m.
Answer: the length of the sea wave is λ = 2 m.
