Question

A new band sensation is playing a concert and recording it for a live album to be released this summer. Select all the statements that are true for band producing sound.

a. The produced sound waves are electromagnetic waves.


b. Producing sound changes the wave from an electromagnetic wave to a mechanical wave.

c. The frequency or amplitude of the sound waves will change if the singer varies their voice.


d. The produced sound waves are mechanical waves.


e. Producing sound changes the wave from mechanical wave to an electromagnetic wave.

f. Producing the sound does not change the wave type.

g. The frequency or amplitude of the sound waves will not change.

Answer 1

c. The frequency or amplitude of the sound waves will change if the singer varies their voice.

d. The produced sound waves are mechanical waves.

f. Producing the sound does not change the wave type.

g. The frequency or amplitude of the sound waves will not change

These statements are true. Sound waves are mechanical waves, meaning they require a medium to travel through, such as air or water. Producing sound involves creating vibrations in the medium, which then propagate as sound waves. The frequency and amplitude of the sound waves will change depending on the characteristics of the source producing the sound. However, producing sound does not change the type of wave from mechanical to electromagnetic, or vice versa
