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, A = 45 cm = 0.45 m Speed of the wave is given by: 175 × 0.45 V= 7.87 m/s So, the speed of the wave is 7.87 m/s Hence, this is the required solution.
