# The end correction of a resonance column is 1 cm. If the shortest length resonating with the tuning fork is 10 cm, the next resonating length should be Option 1) 28 cm Option 2) 32 cm Option 3) 36 cm Option 4) 40 cm

D Divya Saini

given  $e= 1 cm$

for first resonance

$\frac{\lambda }{4}=l_{1}+e=11cm$

for second resonance

$\frac{3\lambda }{4}=l_{2}+e=l_{2}=3*11-1=32cm$

Option 1)

28 cm

This is incorrect

Option 2)

32 cm

This is correct

Option 3)

36 cm

This is incorrect

Option 4)

40 cm

This is incorrect
