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:
Longitudinal waves travel through air forming compressions and rarefactions
The correct answer is:
In case of longitudinal waves in which the vibration of the medium is parallel to the direction of the wave travels and displacement of the medium is in the same or opposite direction of wave travels
