Column I shows four systems, each of the same length ' \( L \) ', for producing of a system called
\( \mathrm{P} \)
fundamental frequency, whose wave length is denoted as \( \lambda_{f} \). Match each system with statements given in Column II describing the nature and wavelength of the standing waves
