Question

The region of minimum density through which a wave propagates is called:
(A) Compression
(B) Rarefaction
(C) Crest
(D) Trough

Answer 1

Answer:

(A) Compression

Explanation:

Compression is the region of high pressure and rarefaction is the region of low pressure. Pressure is related to the number of particles of a medium in a given volume. More density of the particles in the medium gives more pressure and vice versa.
