Question

Propagation of sound can be visualized as propagation of density variations or pressure variations in the medium. Comment.

Answer 1

When a vibrating object (prong of a tuning fork) moves outward, it pushes and compresses the air in front of it creating a region of high pressure. This region is called a compression. ... Thus, propagation of sound may be visualised as propagation of pressure variations or density variations in the medium.

i hope this answer helps..

mark me as a brainliest..

Answer 2

Answer:

Yes

Explanation:

It can be visualized on the basis of these variations because density changes the speed of sound and the pressure also changes its speed.
