Homework Help: Physics

Posted by Luricela on Monday, May 31, 2010 at 11:50am.

A flute is designed to play middle C (262 Hz) as the fundamental frequency when all the holes are covered. The length of the flute is 0.655 m. Assume the air temperature is 20C. How far from the end of the flute should the hole be that must be uncovered to play F above middle C (349 Hz)?

I used... Speed of sound in air= 343 m/s, speed of sound in helium= 1005 m/s
and got 0.4914040115 cm but it was marked wrong.
