Question

You have a Coke bottle with an air cavity
that is 0.220 m deep. You add water to
the bottle, shortening the column, so
that when you blow across the top, it
plays a 528 Hz fundamental. How tall is
the water column in the bottle?

    Answer: 0.0576

    Explanation:

    The equation for fundamental frequency for closed pipes is as follows:

    f(1) = v/4L

    In which v is the speed of sound (343 m/s) and L is the length of the pipe. Therefore:

    528 = 343/4L

    x = 0.1624

    This is not the answer as you still need to subtract it from the original length.

    0.220 – 0.1624 = 0.0576
