Procedure ** 1. Fill the column of the resonance apparatus with water. 2. Choose a tone to resonate and hold it above the tube. Adjust the tube length until you hear the strongest resonance point. 3. Measure the length of the air column and record. 4. Change tones and repeat for 4 to 5 total trials. If you are unable to locate the materials to complete this part of the lab you may use the values in the table below. In addition to these values predict what another length of air and frequency would be in this open ended tube. Length of Air (m) Frequency (Hz) 0.06 1418 0.12 708 0.16 531 0.2 425 Data (15 points) Tone Used (Hz) Air Column Length (m) >=4*Air Column Length
