Two very long string are tial together at the point x = 0 In region x lt 0, the wave speed is `v_(1)`,while in the regon x gt0, the speed is `v_(2)`. A sinusoidal wave is incident on the knot from the left(x lt 0). Part of the wave is redlected and part is transmitted. For X lt 0 the the displacement of the wave is described by y(x,t) = A sin(`K_(1)x-wt`)+B sin (`k_(1)x+wt)`, while for x gt 0, y(x,t)=Csin (`K_(1))x-wt`, where`w//k_(1) =v_(1)"and "w//k_(2) = v_(2)`. Which of the following is /are correct .A. `C/A=(2v_(2))/(v_(1)+v_(2))`B. `B/A=(v_(2)-v_(1))/(v_(1)+v_(2)`C. `B^(2)+(v_(1))/(v_(2))C^(2)=A^(2)`D. A^(2)+(v^(1))/(v_(2))C^(2)=B^(2)` |
