Question

How does the sound produced when there is a box underneath the string look different on the screen of an oscilloscope from the sound when there is no box?

a. The amplitude will decrease.
b. The frequency will decrease.
c. The wavelength will increase.
d. The waveform will remain unchanged.

Answer 1

The waveform of the sound produced when there is a box underneath the string will remain unchanged on the screen of an oscilloscope.

Step-by-step explanation:

When there is a box underneath the string, the sound produced will look different on the screen of an oscilloscope compared to when there is no box. The correct answer is d. The waveform will remain unchanged. The presence of a box underneath the string will not affect the waveform of the sound wave. It may affect other properties like amplitude or frequency, but the waveform will remain the same.
