Weak background noises from a room set up the fundamental standing wave in a cardboard tube of length L = 67.0 cm with two open ends. Assume that the speed of sound in the air within the tube is 343 m/s. (a) What frequency do you hear from the tube? (b) If you jam your ear against one end of the tube, what fundamental frequency do you hear from the tube?

To solve the problem step by step, we will first address part (a) and then part (b). ### Part (a): Frequency heard from the tube with both ends open 1. **Identify the parameters**: - Length of the tube, \( L = 67.0 \, \text{cm} = 0.67 \, \text{m} \) - Speed of sound in air, \( v = 343 \, \text{m/s} \) ...
