Chapter 17, Problem 1PQ

A dog swims from one end of a pool to the opposite end. Is the dog’s motion described as a wave? Explain.

To determine

Explain whether the motion of the dog swimming in water can be described as a wave or not.

Answer to Problem 1PQ

The motion of the dog swimming in water cannot be described as a wave. The dog creates water waves in pool but is itself behaves as a particle.

Explanation of Solution

The dog is modeled as a particle moving from one end to the other end of the pool,. It creates waves in the pool, but it is only the transfer of matter instead of the transfer of energy from one point to the other.

In order to consider as a wave, there must be energy transfer rather than an exchange of matter.

Since the dog is a matter, the transfer of matter can be considered to be a particle.

Conclusion:

Therefore, the motion of the dog swimming in water cannot be described as a wave. The dog creates water waves in pool but is itself behaves as a particle.
