Chapter 9.2, Problem 15R

To determine

The process to shake the end of the rope to make the wavelength shorter.

Answer to Problem 15R

The process to shake the end of the rope to make the wavelength shorter is to shake the rope with higher frequency.

Explanation of Solution

Introduction:

A wave can be generated by shaking the end of along rope and that wave will be a transverse wave as the particles will vibrate in perpendicular direction of wave propagation.

As the frequency of the shaking of rope increases the wavelength will be shorter. To shorten the wavelength, the shaking of rope from end should be done quickly. The process to shake the end of the rope to make the wavelength shorter is to increase the frequency of shaking.

Conclusion:

Thus, the process to shake the end of the rope to make the wavelength shorter is to shake the rope with higher frequency.
