Chapter 22, Problem 6Q

To determine

To Explain: Whether the lead-in-wires need to be equal in length so that there will not be a time lag between speakers.

Explanation of Solution

Introduction:

According to Maxwell, a changing electric field can produce a magnetic field in an empty space. These changing fields can then produce a wave called an electromagnetic wave which can travel through space.

The time difference will be very small if the length of the lead-in-wires will be changed because the electromagnetic wave travels nearly at the speed of light. So, time difference between the signals will be almost negligible to the ears to hear. The important part is to check the resistance of the wires of the speakers. Hence, it is not necessary to be the lead-in-wires to be of equal length.

Conclusion:

The difference in length would need to be genuinely huge with the end goal for the person to truly see a distinction in the sound output.
