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

A tuning fork of frequency n is held near the open end of tube, the tube is adjusted until resonance occurs. If the two shortest lengths to produce resonance are L_1 and L_2 , then the speed of the sound is

A tuning fork vibrating with a frequency of 500 Hz is kept close to the open end of a tube filled with water, as shown in figure. The water level in the tube is gradually lowered When the water level is 17 cm below the open the open end, maximum intensity of sound is heard. If the room temperature is 20^(@) C, the speed of sound in air at the temperature is

In Quincke's experiment the sound detected is changed from a maximum to a minimum when the sliding tube is moved through a distance of 2.50 cm. Find the frequency of sound if the speed of sound in air is 340 m s^-1 .

A tuning fork vibrating with a frequency of 512 Hz is kept close to the open end of a tube filled with water , figure. The water level in the tube is gradually lowerd. When the water level is 17cm below the open end, maximum intensity of sound in heard. If the room temperature is 20^(@)C , calculate (a) speed of sound in air at room temperature. (b) speed of sound in air at 0^(@)C (c) if the water in the tube is replaced with mercury, will there be any difference in your observations?
