Question

The higher the amplitude of sound,

• A. the less compressed is the air at compressions.
• B. the lesser the density of air at compressions.
• C. the more compressed is the air at compressions.
• D. the denser the air at rarefactions.

Answer 1

The correct option is C the more compressed is the air at compressions.

The higher the amplitude of sound, the more compressed is the air at compressions. It also results in an increase in density at compressions. Similarly, rarefactions will experience lower values of density and pressure.
