Vibrating tuning fork of frequency `n` is placed near the open end of a long cylindrical tube. The tube has a side opening and is fitted with a movable reflecting piston. As the piston is moved through `8.75 cm`, the intensity of sound changes from a maximum to minimum. If the speed of sound is `350 m//s`. Then `n` is

A vibrating tuning fork of frequency n is placed near the open end of a long cylindrical tube. The tube has a side opening and is also fitted with a movable reflecting piston. As the piston is moved through 8.75 cm, the intensity of sound just changes from a maximum to minimum. If the speed of sound is 350 metre per second, the value of n is N^3 then N is.

A long cylindrical tube carries a highly polished piston and has a side opening . A tuning fork of frequency n is sounded at the open end of the tube . The intensity of the sounded heard by the listener changes if the piston is moved in or out. At a particular position of the piston he hears a maximum sound . When 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
