TI QUESTIONS 1. Suppose that the laboratory temperature were 5 °C higher than the temperature at which you performed the experiment. Explain what effect(s) this would have on the experimental results. 2. Say the water in the tube was at the level for the tube length L, of the first resonance of the first tuning fork. (a) Could another tuning fork with a frequency lower than that of the first tuning fork produce a resonance? (b) Could another tuning fork of some higher frequency produce a resonance? (c) If your answer is yes in either case, what would be the frequency of the other fork? Name Lab Partner(s) Section, Air Column Resonance. The Speed of Sound in Air 3. What are the resonant frequencies for an open organ pipe of fixed length L? (Show your sketches and calculations.) Date 4. (Optional). The uppermost antinode (Fig. 1) is slightly above the open end of the tube by an amount E (called the end correction). (a) Compute E from the data for each tuning fork. (b) Compare the computed E's with the theoretical values given by the equation E-0.4 X I.D., where I.D. is the inner diameter of the tube.
