The water level in a vertical glass tube 1.00 m long can beadjusted to any position in the tube. A tuning fork vibrating at716 Hz is held just over the open top end of the tube, to set up astanding wave of sound in the air-filled top portion of the tube.(That air-filled top portion acts as a tube with one end closed andthe other end open.) take the speed of sound to be 343 m/s. a) forhow many different positions of the water level will sound from thefork set up a resonance in the tube's air-filled portion? What arethe b) least and c) second least water height in the tube forresonance to occur?
