PhysicsEasysingle choice

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

Options:

Answer:

Solution:

Given: $e = 1 cm$

For first resonance,

$\frac{λ}{4} = l_{1} + e = 11 cm$

For second resonance,

$\frac{3 λ}{4} = l_{2} + e \Rightarrow l_{2} = 3 \times 11 - 1 = 32 cm$
