Explanation / Answer
given that length of tube = L = 122cm = 1.22m when the tube is open at both ends first harmonic wave length = 1= 2L = 2*1.22 = 2.44m second = 2= L = 1.22m third = 3= 2/3*L = 2/3 * 1.22 =0.81m 2.44m,1.22m,0.81m when the tube is open at one end first harmonic = 1= 4L = 4 * 1.22=4.88m third harmonic = 3= 4L/3= 4.88/3 =1.62m fifth harmonic = 5= 4L/5 = 0.976m 4.88m,1.62m,0.976m
