A vuvuzela is a simple horn, typically 0.65 m long, that fans use to make noise at sporting events(Figure 1). What is the frequency of the fundamental note produced by a vuvuzela? Assume a sound speed of 343 m/s.

11. The speed of sound in the air inside a 0.65-m long gas column is 340 m/s. What is the fundamental resonant frequency of this air column if it is (a) open at one end and closed at the other end? (b) open at both ends?
A plunger can be moved back and forth in a hollow tube that is L
= 150 cm long with two open ends. A stretched wire is placed near
the open end, as shown in the figure. The l = 50.0 cm long, 5.0
gram wire is fixed at both ends and oscillates in its fundamental
mode. By resonance (meaning that the frequency of the string equals
the frequency of the air column in the tube), the string sets the...
