Question
Longitudinal waves are those ___.
- In which the particles of the medium vibrate along the direction of motion of the wave
- In which the particles of the medium vibrate perpendicular to the direction of motion of the wave
- Which does not require a material medium for their propagation
- None of the above
Hint:
- Particles vibrates parallel to the direction of wave propagation.
The correct answer is: In which the particles of the medium vibrate along the direction of motion of the wave
- Longitudinal waves are a type of mechanical wave, requires medium for propagation.
- Medium particles vibrates along/parallel to the direction of wave propagation.
- Therefore, longitudinal waves are those in which the particles of the medium vibrate along the direction of motion of the wave.
- So, the correct option is a.

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
