A vibrating tuning fork is held above column of air. Reservoir is raised and lowered to change water level and length of column of air. Shortest length of air that produces resonance is .25. Next resonance is heard when air column is 0.80m long speed of sound in air is 343 m/s and spped of sound in water is 1490 m/s Wavelength of standing wave is 1 m frequency that produces this standing wave is 343 Hz wavelength of sound wave is 4.34 m. The water level is lwered again until a third resonance is heard. Calculate the length of air column that produces this third resonance.
