On a summer afternoon, a pipe that is open at both ends is held vertically with one end submerged in water as shown in Figure P13.70. If a 220-Hz tuning fork is held over the end of the tube, it induces resonance when the top of the tube is from the surface of the water and when it is from the surface. (a) What was the velocity of sound in the air at that time on that hot summer day? (b) What was the air temperature? Is this method a good way to measure temperature? Why or why not?
