Question
When a longitudinal wave travels through a medium, the particles of the medium show compression and Rarefaction. What happens when compression takes place in the medium?
- The Density of the medium decreases.
- The pressure of the medium decreases.
- The molecules of the medium come closer to each other.
- The Wavelength of the wave increases.
Hint:
The molecules of the medium come close to each other
The correct answer is: The molecules of the medium come closer to each other.
places where particles of the medium crowd closer together are called compressions.

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:
