Standing waves are neat patterns that happen when two waves with the same speed and height move in opposite directions.

These waves create special spots.

• Some spots are where nothing moves; these are called nodes.
• Other spots are where the movement is the strongest; these are called antinodes.

How They Form:

1. Interference: This happens when two waves meet each other.
2. Fixed boundaries: When the waves hit a wall or something and bounce back, they get even stronger.

It's kind of like when you pluck a guitar string and see those cool wave patterns!
