In the oceans, the wavelength reaches 270m, and the oscillation period is 13.5s.

In the oceans, the wavelength reaches 270m, and the oscillation period is 13.5s. Determine the propagation speed of such a wave.

The solution of the problem:

To solve this problem, you need to apply the formula for finding the wavelength, which looks like this:

λ = v * T;

λ is the wavelength;

v is the propagation speed;

T is the oscillation period.

Now we will find the speed of propagation of the wave using the formula for finding the wavelength, transforming it.

v = λ / T = 270 / 13.5 = 20 (m / s).

Answer: 20 (m / s).
