What are the amplitudes at node and antinode in a stationary wave? Explain.
(N/A) In a stationary wave formed by the superposition of two identical waves traveling in opposite directions,the amplitude varies with position.
$1$. At a node,the two waves interfere destructively,resulting in a displacement of $0$. Thus,the amplitude at a node is $0$.
$2$. At an antinode,the two waves interfere constructively,resulting in a maximum displacement. If each component wave has an amplitude $A$,the amplitude at the antinode is $2A$.
