A wire of uniform linear density is stretched between two fixed points along the X-axis with one fixed end as the origin. A point on it is displaced along Y-axis and released. A steady wave form is formed along the length of the wire. This wave form is given by:

(A):y = R sin (Pt - Qx)
(B):y = R sin (Pt + Qx)
(C):y = R sin (Pt) cos (Qx)
(D):y = R cos (Pt) sin (Qx)
