For 20 s, the float performs 40 oscillations on waves, and the distance between adjacent wave humps is 1.5 m. What is the speed of wave propagation?

N = 40.

t = 20 s.

λ = 1.5 m.

V -?

The speed of propagation of waves V is determined by the formula: V = v * λ, where v is the vibration frequency, λ is the wavelength.

The wavelength λ is the distance between adjacent wave humps.

The frequency of oscillations v is the number of oscillations per unit of time. The oscillation frequency v is determined by the formula: v = N / t, where N is the number of oscillations, t is the time during which the oscillations were made.

The formula for determining the speed of the wave V will take the form: V = N * λ / t.

V = 40 * 1.5 m / 20 s = 3 m / s.

Answer: the wave propagation speed is V = 3 m / s.
