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

  1. A32 cm
  2. B40 cm
  3. C28 cm
  4. D36 cm

Correct answer

A. 32 cm

Step-by-step solution

Given: e = 1   cm . For first resonance, λ 4 =   l 1 + e = 11   cm . For second resonance, 3 λ 4 =   l 2 + e   ⇒   l 2 = 3   × 11 - 1 = 32   cm .
