Vedclass · Answer

(A) When a pulse of a wave train travels along a stretched string and reaches a fixed end,it undergoes reflection.According to the boundary conditions for a fixed end,the displacement at the boundary must be zero at all times.This results in a phase change of $\pi$ $(180^{\circ})$ for the reflected pulse compared to the incident pulse.However,the velocity of the wave after reflection is reversed in direction,but the magnitude remains the same.Therefore,the pulse is reflected back with a phase change of $180^{\circ}$ and its velocity is reversed.

$A$ pulse of a wave train travels along a stretched string and reaches the fixed end of the string. It will be reflected back with
