Chapter 14, Problem 58A

To determine

The difference between the frequency of a hand and the frequency of a wave.

Answer to Problem 58A

The frequency of hand remains the same because the hand is the one which is generating the wave itself.

Explanation of Solution

Introduction:

The frequency of the hand remains the same because, when the hand is moved it generates waves on its own.The frequency of the wave is similar to the frequency of the vibrations that are caused by the waves.

For example higher frequency can be generated in rope the rope must be moved up and down quickly. It takes more amount of energy with a low frequency and has same amplitude.

The frequency of wave is defined as the number of waves which are produced in a given period of time. The wave has a series of crest and troughs.

The highest point present on a wave is called as crest and the lowest point is called as trough.

In transverse waves the waves the particles of the medium move perpendicular to the direction in which the wave moves.

Transverse waves are produced when you shake one end of the spring back and forth. The frequency of the hand is similar to the frequency of wave as your hand itself generates the wave.

Conclusion:

Hence, the frequency of the hand is same because the hand generates the wave itself.
