Question

In Resonance tube experiment, if 400 Hz tuning fork is used, the first resonance occurs when length of air column in the tube is 19 cm. If the 400 Hz tuning fork is replaced by 1600 Hz tuning fork, then to get resonance, the water level in the tube should be further lowered by (take end correction = 1 cm)

Solution

The correct options are
A 5 cm
C 15 cm
For first resonance with 400 Hz tuning fork,
leq=V4f0=V4(400)=(19+1)=20 cm
If we use 1600 Hz tuning fork
V4f0=V4(1600)=204=5 cm

for resonance,
leq=V4f0,3V4f0,5V4f0,7V4f0...1 cm+l=5 cm, 15 cm, 25 cm, 35 cm, 45 cm...l=4 cm, 14 cm, 24 cm, 34 cm, 44 cm...water level should be further lowered by
24−19=5 cm34−19=15 cm
