Question

You have two synchronously vibrating objects in an infinitely large pool. The distance between them is 6.0 m. Their frequency of vibration is 2.0 Hz and the wave speed is 4.0 m/s. The vibrations are sinusoidal. Neglect the decrease of amplitude with distance.

A. Find a minimum distance from one of the objects to a location between objects where the water does not vibrate. Note that the required location should not coincide with the location of the chosen object.

B.

Find a minimum distance from one of the objects to a location between objects where the water vibrates with the largest amplitude. Note that the required location should not coincide with the location of the chosen object.
