A narrow hollow tube of length L = 3.50 m is open at both ends and sits on two sawhorses, like the wood is resting on two sawhorses in the picture to the right. The tube exhibits nodes where it is touching the sawhorses. A wind is blowing and the tube is "moaning". The temperature of the air in the room is 17 C. Take the speed of sound to be 340 m/s.

1. Using the universal wave equation, determine the speed of the wave.

2. What is the theoretical speed of sound according to the temperature of the room?
