A closed organ pipe has a length of 2.40 m?

  1. Feb 27, 2014 #1
    A closed organ pipe has a length of 2.40 m.

    a.) What is the frequency of the note played by the pipe? Use
    343 m/s as the speed of sound.

    b.) When a second pipe is played at the same time, a 1.40 Hz beat note is heard.
    By how much is the second pipe too long?

    The a.) problem's solution is 35.7 Hz. and b.) problem's solution is 0.10 m

    The actual problem here is that I don't know how to properly solve b.)

    Please show some work.
    - What are the relevant equations for this problem?
    - What have you done to try to solve the problem?

    This is the correct section.So as the Mentor said,
    - What are the relevant equations for this problem?
    - What have you done to try to solve the problem?

    Only then will we be able to help you.Sorry :frown:
    If that was a question given to you,you must be knowing some relevant equations or some method to solve it.
