An organ pipe is open at one end and has a length of 3 m. What is its fundamental frequency if the speed of sound is 336 m/s?

and it is closed on the other? the pipe is 1/4 wavelength long.

f*4Lengthpipe=336

To find the fundamental frequency of an open organ pipe, we need to use the formula:

f = v / (2L)

where:
f = fundamental frequency (in Hz)
v = speed of sound (in m/s)
L = length of the organ pipe (in m)

Given:
v = 336 m/s
L = 3 m

Plugging the given values into the formula, we have:

f = 336 / (2 * 3)

Now, let's calculate the answer:

f = 168 / 6
f = 28 Hz

Therefore, the fundamental frequency of the open organ pipe is 28 Hz.
