Question

What is the frequency of a wave with a speed of 28.2 m/s and a wavelength of 12.2 m?

Answer 1

The frequncy is given as

$$f= \dfrac{c}{\lambda}$$

where $c = 28.2m/s$ is the speed of wave, and $\lambda = 12.2m$ is the wavelenght.

Thus, obtain:

$$f= \dfrac{28.2m/s}{12.2m} \approx 2.3s^{-1} = 2.3\space Hz$$

Answer. 2.3 Hz.
