A resonating tube of length l , open at one end, is partially filled with water. When placed in gaseous medium-X, a water column of height l / 5 generates the third harmonic using a tuning fork with frequency . When placed in gaseous medium-Y, a water column of height l / 3 generates the fifth harmonic using the same tuning fork. The ratio v_ X : v_ Y of the velocity of sound in medium- X to medium- Y is
