A sine wave y=sin `(2pix-2pit+pi//3)` is propagating in the medium. Match the description of the motion of particles of the medium with entries in columnI
`{:(,"Column-I",,"Column-II"),("(A)",x=1/3"m, t"=1/3sec,,"(P)Velocity is in positive y direction"),("(B)",x=1/3"m, t"=1sec,,"(Q)Velocity is in negative y direction"),("(C)",x=1"m, t"=1/3sec,,"(R)Particle is stationary"),("(D)",x=1"m, t"=1sec,,"(S)Particle has positive displacement"),(,,,"(T)Particle has negative displacement"):}`

Explanation

Refrection at movable boundaries no phase reversal takes palce but at rigid bondaries phase reversal of `180^(@)` takes place
