ZOOM+1) Suppose we have an air column 80cm long with one open end and one closed end.(a) Find (i.e. derive) an expression for the resonant frequencies of the air column interms of the length L of the air column, the speed of sound v, and the harmonicnumber n. Don't simply write the equation – show me how you obtain it bysketching several resonant standing waves.(b) What are the three lowest resonant frequencies in this air column (numerical values)?Take the speed of sound in air to be 343 m/s.
