Tapping the surface of a pan of water generates 17.5 waves per second. if the wavelength of each wave is 45 cm, what is the speed of the waves?

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,

Speed of the wave is given by :

v = 7.87 m/s

So, the speed of the wave is 7.87 m/s. Hence, this is the required solution.
