1. Students in a physics lab are asked to find the length of an air column in a tube close at one end that has a fundamental frequency of 341.3 Hz They hold the tube vertically and fill it with water to the top, then lower the water while a 341.3 Hz tuning fork is rung and listen for the first resonance. A. What is the air temperature if the resonance occurs for a length of 0.2483 m? (use velocity of sound: v= 331.4 m/s +0.6 x Tc) (3 pts.) B. At what lengths will they likely observe the 2nd, 3rd, and 4, resonances (1″, 2nd, and 3rd, overtones)? (3 pts. C. The students next want to cut a pipe of the shortest length so that it resonates with the same tuning fork when open at both ends. How long should it be? (3 pts
