Answer:
17.55 m/s
Explanation:
The number of times a wave will pass through a particular point is called frequency so, here the frequency is 3 Hz = f
The distance which is measured between two troughs or crests in a wave is called wavelength so, here the wavelength is 5.85 m = [tex]\lambda[/tex]
Velocity is given by
[tex]v=f\lambda\\\Rightarrow v=3\times 5.85\\\Rightarrow v=17.55\ m/s[/tex]
The propagation speed of the waves is 17.55 m/s
