What is the fundamental frequency of a tube that is .5 m long, if the speed of sound in air is 340 m/s and the tube is closed on one end?
The fundamental frequency of a tube that is closed on one end is given by the formula:
f = v / 4L
where:
f = fundamental frequency
v = speed of sound in air
L = length of the tube
Substituting the given values:
f = 340 m/s / (4 * 0.5 m)
f = 340 / 2
f = 170 Hz
Therefore, the fundamental frequency of the tube is 170 Hz.
