Question
A longitudinal wave is produced by the vibration of an object. It travels through a medium such as air by forming alternate regions of compression and Rarefaction of air molecules. As a longitudinal wave travels through air, the regions of compression and Rarefaction in it can be shown as:
Hint:
C
The correct answer is:
C shows rarefaction and compression in a longitudinal wave.
