The wave from the steamer sailing on the lake reached the shore in 1 minute. The distance between 2 adjacent “crests” of the wave is 1.5 m, and the time between two successive impacts on the shore is 2 s. How far from shore did the steamer sail?

To find the distance at which the steamer passed from the coast, we use the formula: S = V * t = λ / T * t.

Variables: λ – distance between adjacent ridges, length (λ = 1.5 m); T is the time between two shocks on the shore, period (T = 2 s); t is the duration of the wave movement from the steamer to the shore (t = 1 min = 60 s).

Let’s perform the calculation: S = λ / T * t = 1.5 / 2 * 60 = 45 m.

Answer: The steamer passed at a distance of 45 m from the coast.
