Part (A) Select the image from the options provided showing the gas pressure for the third harmonic of a pipe with two open ends.
Part (B) Calculate the wavelength λ3 in m for the third harmonic in the pipe with two open ends.
Part (C) Calculate the frequency f1 in Hz for the fundamental harmonic in the pipe with two open ends.
Part (D) Select the image from the options provided showing the gas pressure for the third mode of a pipe with one open end and one closed end. (the third mode is the third possible excitation).
Part (E) Calculate the frequency f1 in Hz for the fundamental harmonic in the pipe with one open and one closed end.
