The water level in a vertical glass tube 1.300 m long can be adjusted to any position in the tube. A tuning fork vibrating at 676.00 Hz is held just over the open top end of the tube. Assume a speed of sound of 343 m/s. What is the greatest depth of water for which there will be resonance in the air in the tube?
