Problem

Column I shows four systems, each of the same length

L

, for producing standing waves. The lowest possible natural frequency of a system is called its fundamental frequency, whose wavelength is denoted as

\lambda_f

. Match each system with statements given in Column II describing the nature and wavelength of the standing waves. [2011]

Column I	Column II
(A) Pipe closed at one end	(p) Longitudinal waves
(B) Pipe open at both ends	(q) Transverse waves
(C) Stretched wire clamped at both ends	(r) $\lambda_f = L$
(D) Stretched wire clamped at both ends and at mid-point	(s) $\lambda_f = 2L$
	(t) $\lambda_f = 4L$
