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 $2A$.

$A$ standing wave exists in a string of length $150 \ cm$,which is fixed at both ends with rigid supports. The displacement amplitude of a point at a distance of $10 \ cm$ from one of the ends is $5\sqrt{3} \ mm$. The nearest distance between two points,within the same loop and having a displacement amplitude equal to $5\sqrt{3} \ mm$,is $10 \ cm$. Find the maximum displacement amplitude of the particles in the string (in $mm$).
