How does the frequency of vibration of a small object floating in water compare with the number of waves passing it each second?
Solution 25E Step 1: Consider we have kept a small object on the surface of the water and initially water and the small object is at rest. If we create a disturbance anywhere in the water, ripples will be formed as the waves and the small object will also move similar to the motion of water molecules since it is residing inside the medium. So, the small object will experience an up and down motion as vibrations. The up and down motion will have a similar time period of waves generated in water. Since the time periods are same, the frequency of the waves formed in water and the frequency of vibration of the small object will be same. Conclusion: The number of waves passing the small object in each second and the frequency of its vibration will be same.
