In a resonance column experiment, the first resonance is obtained, when the level of the water in tube is 20 cm from the open end. Resonance will also be obtained when the water level is at a distance of

Options

  1. A40 cm from the open end
  2. B60 cm from the open end
  3. C80 cm from the open end
  4. D90 cm from the open end

Correct answer

B. 60 cm from the open end

Step-by-step solution

Given, 4 =20 ~cm Next resonance will be obtained at 3 4 =60 ~cm
