Question

how does density and pressure vary in compression and rarefaction lesion of sound waves​

Answer 1

answer: a. The region in a sound wave, with higher pressure and density is called compression and that with low pressure and density is called rarefaction. ... The total number of compressions and rarefactions produced per second in a sound wave is 1000.

Answer 2

density and pressure are directly proportional to compression.

sound waves travel fastest in solid objects and there speed is directly proportional to pressure.
