Expert Answer
Let v be the velocity of sound , Lc is length of pipe that has closed end at one side and Lo is length of pipe that has open sides at both end.
From figure we see that second overtone of one end closed pipe equals third overtone of both end open pipe, then we have
4 [ v / ( 2 Lo ) ] = 5 [ v / (4 Lc ) ]
from above expression, we get
Lo / Lc = 8/5 = 1.6
