Question

Water waves in a small tank are .06 m long. They pass a given point at a rate of 14.8 waves every three seconds. What is the speed of the water waves? What is the period of these water waves?

Answer 1

The frequency:

$$f=\frac{14.8}{3}Hz$$

The speed of the water waves:

$$v=\lambda f=0.06\frac{14.8}{3}=0.296\frac{m}{s}$$

The period of these water waves:

$$T=\frac{3}{14.8}=0.203\ s$$
