What is the oscillation period of the wave source if the wavelength is 2 m, and v = 5 m / s

Given:

c = 5 meters per second – wave propagation speed;

L = 2 meters – wavelength.

It is required to determine T (seconds) – the period of wave oscillations.

Let’s find the frequency of the wave oscillations:

c = L * u, hence:

u = c / l = 5/2 = 2.5 second-1.

Then the wave oscillation period will be equal to:

T = 1 / u = 1 / 2.5 = 0.4 seconds.

Answer: the wave oscillation period is 0.4 seconds.
