Some students are trying to find the depth of an empty well. They drop a stone into the well and measure the amount of time taken for it to hit the bottom of the well. They find the time to be 0.90 s, with an experimental uncertainty of 5.0%. Since the students need to know the well's depth with more precision, they create a sound tone at the top of the well, and they notice the sound sets up a standing wave when its frequency is 285 Hz. Assuming the speed of sound on that day was 342 m/s... a. What are the minimum and maximum depths the well could have? (3.6 m, 4.4 m) b. What is the wavelength of the sound wave used by the students? (1.2 m) c. A tube that is open on one end and closed at the other, like a well, will form standing waves in the following patterns. Using this information, determine the depth of the well. (3.9 m) no
