A tube is open only at one end. A certain harmonic produced by the tube has a frequency of 571 Hz. The next higher harmonic has a frequency of 799 Hz. The speed of sound in air is 343 m/s. (a) What is the integer n that describes the harmonic whose frequency is 571 Hz? (b) What is the length of the tube?
B. A person hums into the top of a well (tube open at only one end) and finds that standing waves are established at frequencies of 36.1, 60.2, and 84.2 Hz. The frequency of 36.1 Hz is not necessarily the fundamental frequency. The speed of sound is 343 m/s. How deep is the well?

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
