A metre-long tube open at one end, with a movable piston at the other end,shows resonance with a fixed frequency source (a tuning fork of frequency 340 Hz ) when the tube length is 25 . 5 cm or 79 . 3 cm . Estimate the speed of sound in air at the temperature of the experiment. The edge effects may be neglected .
