Natural frequency of a system is called its fundamental frequency, whose wavelength is denoted as `lamda_(f)`. Match each system with statements given in Column-II describing the nature and wavelength of the standing waves.

Answer

A, B, C, D

Explanation

A-P,T,B-P,S,C-Q,S,D-Q,R
(A) Sound wave are longitudinal waves `(lambda_f)/2=L implieslambda_f=4L`
(B) (A) Sound wave are longitudinal waves `(lamda_f)/2=L implies lambda_f=2L`
( c )string wave are transervse wave `(lambda_f)/2=L implies lambda_f=L`
(D) string wave are transverse waves `(lambda_f)/2=L implies lambda_f=L`
