Question

Q.2. Show the region of compression and rarefaction in the following diagram.​

Answer 1

Compressions:

• These are regions in a longitudinal wave (or pressure waves) where the medium particles are closer to one another.

• Due to compactness of medium particles, the density in that region is higher.

Rarefactions:

• These are regions in a longitudinal wave (or pressure waves), where the particles of the medium are present far from one another.

• This means that the density of medium in that area is lesser as compared to Compressions.

Answer 2

Compressions and rarefactions

Explanation:

• Longitudinal waves are comprised of compressions and rarefactions.
• Compressions are those parts of wave where particles of wave are close together whereas rarefactions are those regions of the longitudinal wave where particles are farther apart.
• The region where the medium is compressed is referred to as a compression . The region where the medium is spread out is referred to as a rarefaction.
• The image has been attached to depict compressions and rarefactions in the diagram.
