Answer 2

Hi
Here is ur answer :-
A node is a point along a standing wave where the wave has minimum amplitude. For instance, in a vibrating guitar string, the ends of the string are nodes. By changing the position of the end node through frets, the guitarist changes the effective length of the vibrating string and thereby the note played.

Antinodes are formed in open boundary and particles at that points have maximum amplitude.

Hope it helps u
