Label both the nodes and the anti-nodes. a) The 3rdharmonic of a string b) The 4thharmonic of an air column open at both ends c) The 5thharmonic of an air column that is opened at one only. 3. Short Answer.Provide the answer in the space provided. Question Answer a) What is the air temperature if the speed of sound is 355 m/s? __________ b) A 512-Hz tuning fork produces a sound wave with a wavelength of 68 cm. With what speed does the sound wave travel? __________ c) An object produces a sound wave with a wavelength 75.0 cm. If the speed of sound is 350 m/s, the frequency of the sound is __________ INQUIRY 4. A standing wave with five loops is generated in a string. If the waves travel at 17.5 m/s with a frequency of 1.40 x 102Hz, how long is the string? Include a diagram. 5. An air column (fixed at one end) is caused to resonate at the 3rdharmonic. If the air temperature is 020Cand the frequency of the sound is 220 Hz. Determine the frequency for the 5thharmonic. Assume a constant length. APPLICATION 6. In an elementary school track meet, the starter is usually located on the field near lane #1. Assuming an 8 lane track, with each lane being roughly 1m in width, discuss why it might be advantageous to be closest to the starter’s “pistol”.
