Two identical cylindrical pipes, each of length \(L\), are filled with air. Pipe 1 is open at both ends and vibrates in its fundamental mode at frequency \(f_1\). Pipe 2 is open at one end and closed at the other end. Which row in the table correctly identifies the fundamental frequency of Pipe 2 in terms of \(f_1\), the harmonics allowed in Pipe 2, and the ratio of the frequency of the second resonant standing wave mode in Pipe 2 to its fundamental frequency?

	Fundamental Frequency of Pipe 2	Allowed Harmonics in Pipe 2	Ratio of 2nd Resonant Mode Frequency to 1st Resonant Mode Frequency
(A)	\(2f_1\)	All integer harmonics (\(n = 1, 2, 3, \dots\))	\(2\)
(B)	\(\dfrac{1}{2}f_1\)	Odd integer harmonics only (\(n = 1, 3, 5, \dots\))	\(3\)
(C)	\(\dfrac{1}{2}f_1\)	All integer harmonics (\(n = 1, 2, 3, \dots\))	\(2\)
(D)	\(2f_1\)	Odd integer harmonics only (\(n = 1, 3, 5, \dots\))	\(3\)
