Questions
A source of sound placed at the open end of a resonance column sends an acoustic wave of pressure amplitude inside the tube. If the atmospheric pressure is then the ratio of maximum and minimum pressure at the closed end of the tube will be
detailed solution
Correct option is A
Maximum pressure at closed end will be atmospheric pressure adding with acoustic wave pressure So ρmax=ρA+ρ0 and ρmin=ρA−ρ0Thus ρmaxρmin=ρA+ρ0ρA−ρ0Talk to our academic expert!

A tube of certain diameter and of length 48 cm is open at both ends. Its fundamental frequency of resonance is found to be 320 Hz. The velocity of sound in air is 320 m/s. One end of the tube is now closed, considering the effect of end correction, calculate the lowest frequency of resonance for the tube (in Hz).
