Solution

The correct option is B Adiabatic
According to Laplace, the rarefaction and compression takes place too fast that the element of the gas medium which is compressed or rarefied does not get enough time to exchange energy with the surrounding and so the process is adiabatic.
Hence the pressure variations in the propagation of sound waves are adiabatic.

Q. Propagation of sound can be visualized as propagation of which of the following variations in the medium?

Three statements regarding the propagation of sound waves.

I Sound waves propagate through a series of crests and troughs.

II Sound waves require a material medium for their propagation.

III The propagation of sound waves is attributed to the motion of particles.

Among the given statements,

The pressure variation equation of a sound wave propagating in a medium with pressure amplitude $P_{0}$ is

$P = P_{0} s i n ω (t - \frac{x}{v})$

Inference:

In the tube where this wave is propagating if we measure pressure, then the maximum pressure measured will be _{$P_{0}$}atm and Minimum pressure measured will be _{$- P_{0}$}atm as maximum $&$ minimum values of sin $θ$ is (+1/-1).
