A long cylindrical tube carries a highly polished piston and has a side opening. A tuning fork of frequency n is sounded at the sound heard by the listener charges if the piston is moves in or out. At a particular position of the piston is moved through a distance of 9 cm, the intensity of sound becomes minimum, if the speed of sound is 360 m/s, the value of n is

When piston moves a distance
, path difference change by 2 xs.
the path difference between maxima and consecutive minima=
∴
Or
λ=4x=4×9 cm=36cm=0.36m

∴
Or
λ=4x=4×9 cm=36cm=0.36m
