The wave propagates in an elastic medium at a speed of 20 m / s. Find the oscillation period of the points of the medium if the wavelength is 4 m.
To find out the oscillation period of the points of the considered elastic medium, we will use the formula: T = λ / υ, where λ is the wavelength (λ = 4 m); υ is the propagation speed (υ = 20 m / s).
Let’s make a calculation: T = λ / υ = 4/20 = 0.2 s.
Answer: The oscillation period of the points of the considered elastic medium is 0.2 s.
