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 340Hz ) when the tube length is 25.5cm or 79.3cm. Estimate the speed of sound in air at the temperature of the experiment. The edge effects amy be neglected.

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 340Hz) when the tube length is 0.255m or 0.793m. Estimate the speed of sound in air at the temperature of the experiment. The edge effects may be neglected.

In a resonance tube, using a tuning fork of frequency 325 Hz , the first two resonance lengths are observed at 25.4 cm and 77.4 cm . The speed of sound in air is
