| **What is the wavelength in water if, at a wave propagation speed of 2.4 m / s, a body floating on the water makes 20 vibrations in 10 s.**

Initial data: υ (wave propagation speed) = 2.4 m / s; N (the number of vibrations that a body floating in the water has made) = 20 vibrations; t (duration of body vibrations in water) = 10 s.

1) Define the vibrations of the body in water: T = t / N = 10/20 = 0.5 s.

2) Let’s calculate the wavelength in water: λ = υ * T = 2.4 * 0.5 = 1.2 m.

Answer: The wavelength in water is 1.2 meters.
