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 `100ms^(-1)`. The other end of the string is vibrating in the y-direction so that stationary waves are set up in the string. The possible wavelength`(s)` of these sationary waves is (are)A. `y(t) = A sin (pi x)/(6) cos (50 pi t)/(3)`B. `y(t) = A sin (pi x)/(3) cos (100 pi t)/(3)`C. `y (t) = A sin (5 pi x)/(6) cos (250 pi t)/(3)`D. `y(t) = A sin (5 pi x)/(2) cos 250 pi t` |
