The distance between adjacent wave crests is 1 m, and during 9.8 s the boat swung 3 times (a). What is the speed of wave propagation.
These tasks: λ (distance between adjacent crests of the considered waves, wavelength) = 1 m; t (duration of boat vibrations) = 9.8 s; n (number of boat vibrations) = 3 vibrations.
The speed of propagation of the waves under consideration is determined by the formula: V = λ / T = λ / (t / n) = λ * n / t.
Let’s perform the calculation: V = 1 * 3 / 9.8 ≈ 0.31 m / s.
Answer: The propagation speed of the waves under consideration is 0.31 m / s.
