One end of a taut string of length 3m along the x axis is fixed at x = 0. The speed of the waves in the string is 100 ms. The other end of the string is vibrating in the y direction so that stationary waves are set up in the string. The possible waveform(s) of these stationary waves is (are) TTX 50nt (A) y(t) = A sin (B) y(t) = A sin 6 3 250nt 3 (C) y(t) = A sin COS 5 6 cos (D) y(t) = A sin TTX 3 5 2 Cos 100nt 3 cos 250nt
