A sound wave is passing through air column in the form of compression and rarefaction. In consecutive compressions and rarefactions:
Text Solution
Verified by ExpertsThe correct answer is:
D
Due to compression and rarefactions density of the medium (air) changes. At compressed regions density is maximum and at rarefactions density is minimum.
As density is changing, so Boyle's law is not obeyed.
Bulk modulus remains same.
The time of compression and rarefaction is too small i.e., we can assume adiabatic process and hence no transfer of heat.
