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:
Vibration of particles is parallel to the wave propagation.
The correct answer is:
- Alternate regions of compression and rarefaction of air molecules is shown by pattern given in option c.
- Longitudinal waves are waves in which the vibration of the medium is parallel to the direction the wave travels.
- So, the correct option is c.
