Question

***Please explain your answer

Sound wave propagation is a isentropic process which has a special relationship between pressure and density given by P/rhok = constant What is k? k is the same as gas constant R as found in the ideal gas law p = row RT k is the same as relative density rho as found in the ideal gas law p = rho RT k is a ratio between pressure p and density rho k is a Constant depending on the type of gas measured at a known pressure and temperature k is a constant for a gas derived by taking a ratio of the pressure and the volume

Explanation / Answer

It seems that none of the options other than D seem right. Let me know if I am wrong . thank you.
