a. The recorded waves are mechanical waves.


b. The recorded waves are electromagnetic waves.


c. The wave display does not change the wave type.


d .The the wave display changes the wave from mechanical wave to an electromagnetic wave.


e. The frequency or amplitude of the waves could change.


f. The frequency or amplitude of the waves will not change.


g. The wave display changes the wave from an electromagnetic wave to a mechanical wave.

Answer 1

a. The recorded waves are mechanical waves.

c. The wave display does not change the wave type.

e. The frequency or amplitude of the waves could change.

These statements are true. Recorded sound waves are mechanical waves, meaning they require a medium to travel through, such as air or water. The wave display is a device that displays the shape, frequency, and amplitude of the sound waves. It does not change the type of wave from mechanical to electromagnetic, or vice versa. The frequency and amplitude of the sound waves could change, depending on the characteristics of the source producing the sound.
