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

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

B

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

C

`(P_(A))/(P_(A))`

D

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

A narrow tube of length l and radius r is sealed at one end. Its open end is brought in contact with the surface of water while the tube is held vertical. The water rises to a height h in the tube. The contact angle of water with the tube wall is theta , density of water is rho and the atmospheric pressure is P_(o) . Find the surface tension of the liquid. Assume that the temperature of air inside the tube remains constant and the volume of the meniscus is negligible.
