Two pipes are each \( 2 \mathrm{~m} \) long. One is closed at one end and the other is open at both ends.
\( \mathrm{P} \) The speed of sound in air is \( 340 \mathrm{~m} / \mathrm{s} \). The
W frequency at which both can resonate is :
(1) \( 340 \mathrm{~Hz} \)
(2) \( 510 \mathrm{~Hz} \)
(3) \( 42.5 \mathrm{~Hz} \)
