Question : 20

Total: 60

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 λf. Match each system with statements given in Column II describing the nature and wavelength of the standing waves:

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 sides	(R) λf = L
(D) Stretched wire clamped at both ends and at mid-point	(S) λf = 2L
	(T) λf = 4L
