Given:

The frequency of the wave is f = 3.5 Hz

The wavelength of the wave is

[tex]\lambda\text{ = 0.7 m}[/tex]

To find the speed of the periodic wave.

Explanation:

The speed of the periodic wave can be calculated as

[tex]\begin{gathered} v=f\lambda \\ =3.5\times0.7 \\ =2.45\text{ m/s} \end{gathered}[/tex]

Thus, the speed of the periodic wave is 2.45 m/s
