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?

To find the fundamental frequency of an organ pipe that is open at one end, you can use the formula:

f = (v/2L)

where:
f is the fundamental frequency,
v is the speed of sound, and
L is the length of the pipe.

Plugging in the given values, we have:

f = (336 m/s) / (2 * 3 m)

Simplifying the expression, we get:

f = 56 Hz

Therefore, the fundamental frequency of the organ pipe is 56 Hz.
