Question

Compression is a region of

• A. Low pressure and high density
• B. High pressure and low density
• C. Low pressure and low density
• D. High pressure and high density

Answer 1

The correct option is D High pressure and high density

Compression is the region where the medium particles come closer, i.e., the pressure and density of medium particles in this region are high. However, in case of rarefaction, medium particles are far apart, i.e., pressure and density in this region are low. Sound propagates in the form of compression and rarefaction of the medium particles as shown in the figure.




Hence, the correct answer is option (d).
