Question

In a resonance tube experiment, a tuning fork v resonates with an air column 10 cm long and again resonates when it is 32.2 cm long. Calculate the wavelength of the wave and the end correction.

Answer 1

Data : I₁ = 10 cm, I₂ = 32.2 cm

I₁ + e = \(\frac\lambda4\) and  I₂ + e = \(\frac{3\lambda}4\)

This gives the wavelength of the wave. We have,

This gives the end correction.
