Answer 1

Required Answer:-

The above picture shows a diagram of longitudinal wave which comprises of: compressions and rarefactions.

• The labelling A shows a region of particles closed to each other which means they are in greater density. This region is also known as compression.

Hence, the correct option should be Greatest compression and Greatest density (D$)$

There are two types of waves: Longitudinal wave and Transverse waves. Now the difference is in terms of direction of wave propagation and direction of particles.

• In Transverse waves, there are crests and troughs.
• In longitudinal waves, there are compressions and rarefactions.

Answer 2

Answer:

Required Answer :-

The correct option will be Greatest compression and Greatest density (D)

Explanation :-

It is a diagram that shows compressions and rarefactions. Its a wave that is longitudinal. Longitudinal waves direct wave propagation.

A is showing Compression

It is the greater density part of gas.

Hence D is correct
