0In a Resonance-Coulmn lab experiment to measure the velocity of sound, the first resonance
\( \mathrm{P} \) is obtained at a length \( \ell_{1} \) and the second resonance
W at a length \( \ell_{2} \). Then-
(1) \( \ell_{2}3 \ell_{1} \)
(2) \( \ell_{2}=3 \ell_{1} \)
(3) \( \ell_{2}3 \ell_{1} \)
(4) may be any of the above, depending on the frequency of the tuning fork used.
