Answer:
Speed of the wave is 7.87 m/s.
Explanation:
It is given that, tapping the surface of a pan of water generates 17.5 waves per second.
We know that the number of waves per second is called the frequency of a wave.
So, f = 17.5 Hz
Wavelength of each wave, [tex]\lambda=45\ cm=0.45\ m[/tex]
Speed of the wave is given by :
[tex]v=f\lambda[/tex]
[tex]v=17.5\times 0.45[/tex]
v = 7.87 m/s
So, the speed of the wave is 7.87 m/s. Hence, this is the required solution.
