Before the open end of the tube A, connected by a rubber tube to the ear of the observer, is sounding tuning fork K (Fig.). Pushing the piston from the end of the tube in the A, observers noted a number of consecutive increase and decrease the volume. Find the speed of sound in air υ if the oscillation frequency ν = 440 Hz two successive increase in the intensity of sound corresponds to the distance between the position of the piston Δl equal to 0,375 m.
