One of the harmonic frequencies of tube A with only one end open is 1080 Hz. The next-highest harmonic frequency is 1320 Hz.
a) Find the length of the tube A
b) What harmonic frequency is next highest after the harmonic frequency 600 Hz?
c) What is the number of this next-highest harmonic?
d) Draw the corresponding wave patterns for the harmonic frequency 600 Hz and the next highest harmonic frequency.
