1. What is a node? 2. What is an antinode?
3. What is a wavelength?
Will mark brainliest if correct!!

Node:-

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.

Anti Node:-

An antinode is simply a point along a medium which undergoes maximum displacement above and below the rest position.

Wavelength:-

The total length of circle.

or

Wavelength can be defined as the distance between two successive crests or troughs of a wave.

idk sorry i only needs point for apex

explanation:

number of electrons for neutral cl
