Question

The graph shows the standing wave on a string at two successive instants of time $t_{1}$ & $t_{2}$ . A, B, C, D are the points on the string. (B is the point corresponding to maximum displacement amplitude of standing wave). Select the correct option(s) regarding observations about net mechanical energy for the interval between $t_{1}$ & $t_{2}$ .

TestHub · Accepted Answer

A standing wave is the superposition of two identical waves travelling in opposite directions; each carries energy in its own direction.

Between $t_{1}$ and $t_{2}$ the disturbance shifts so that net energy passes through A toward the right - (A) true, (D) false.

B is the antinode (maximum amplitude point); the two oppositely travelling energy fluxes cancel there at every instant, so no net energy ever crosses B - (B) true.

By the same shift, net energy moves toward the left through C - (C) true. Hence A, B, C.
