Tube

Tuning
Fork
A tuning fork vibrating at 512HZ is held near one end of a tube of length L that is open at both ends,
as shown above. The column of air in the tube resonates at its fundamental frequency. The speed of
sound in air is 340m/s.
(a) Calculate the length L of the tube.
(b) The column of air in the tube is still resonating at its fundamental frequency. Copy the axes below
on to your own paper, and then sketch a graph of the maximum speed of air molecules as they
oscillate in the tube, as a function of position x, from x=0 (left end of tube) to x=L (right end of tube).
(Ignore random thermal motion of the air molecules.) Hint, you are essentially mapping out where
the node(s) are.
