What is the superposition of waves?

• when a single wave splits into two different waves at a point
• when two waves combine at the same place at the same time

What are standing waves?

• waves that appear to remain in one place and do not seem to move
• waves that seem to move along a trajectory

Standing waves are formed --

• by the superposition of two or more waves moving in opposite directions.
• by the superposition of two or more waves moving in the same direction.
• by the superposition of two or more waves moving in perpendicular directions.
• by the superposition of two or more waves moving in any arbitrary directions.
