The fundamental frequency in a pipe closed at one end is 663 Hz. what is the frequency, in hertz, of the m = (2x5)+1) order harmonic? Notes: (the weird formula was just to guarantee that you always get an odd number.. i. e. if your number is 2, then the harmonic is 5. If the number in the formula is 3, then your harmonic is 7)

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
