Question 2

A string 40.0 cm long of mass 8.50 g is fixed at both ends and is under a tension of 425 N. When this string is vibrating in its third OVERTONE, you observe that it causes a nearby pipe, open at both ends, to resonate in its third HARMONIC.
 
  The speed of sound in the room is 344 m/s.
  (a) How long is the pipe?
  (b) What is the fundamental frequency of the pipe?
