An extendible pipe is open at both ends. A speaker can be found a short distance from one end. The speed of sound in air is v = 336 m/s. Assume end effects can be neglected. Speaker Figure 1. A speaker is played through an extendable pipe that is open at both ends. Part 1) A note with a fixed frequency is played through the speaker. The length of the pipe is adjusted until the fundamental mode is found. This nappens when L = 18.4 cm. What is the fundamental frequency? fo = Hz Part 2) The pipe is extended until the next harmonic is heard. What will the length of the pipe be? L = ст

Question

in part 3 there can be more than one answer

An extendible pipe is open at both ends. A speaker can be found a short distance from one end. The speed of sound in air is v = 336 m/s. Assume end effects can be neglected. Speaker L Figure 1. A speaker is played through an extendable pipe that is open at both ends. Part 1) A note with a fixed frequency is played through the speaker. The length of the pipe is adjusted until the fundamental mode is found. This happens when L 18.4 cm. What is the fundamental frequency? fo Hz Part 2) The pipe is extended until the next harmonic is heard. What will the length of the pipe be? L = cm

Part 3) Which of the following statements are true about sound waves in the above pipe? They are transverse waves. If the air inside the pipe was replaced with water, the fundamental frequency would change. The frequency of the ninth harmonic is nine times the fundamental frequency. The length of the pipe for the fifth harmonic is five times the length of the pipe for the fundamental frequency.
