A source of sound placed at the open end...

A source of sound placed at the open end of a resonance column sends an acoustic wave of pressure amplitude `P_(0)` inside the tube. If the atmospheric pressure is `P_(A)`, then the ratio of maximum and minimum pressure at the closed end of the tube will be

A

`((rho_(A)+rho_(0)))/((rho_(A)-rho_(0)))`

B

`((rho_(A)+2rho_(0)))/((rho_(A)-2rho_(0)))`

C

`(rho_(A))/(rho_(A))`

D

`((rho_(A)+(1)/(2)rho_(0)))/((rho_(A)-(1)/(2)rho_(0)))`
