Superposition Principle

Definition

The superposition principle states that when two or more waves or forces are present in the same system, the resulting wave or force is the algebraic sum of their individual effects.

Interference:

When two waves meet, interference occurs and can result in constructive (amplification) or destructive (cancellation) interference.

Standing Wave: A standing wave is formed when two identical waves traveling in opposite directions interfere with each other, creating nodes and antinodes.

Principle of Superposition for Forces: Similar to the superposition principle for waves, this principle states that when multiple forces act on an object simultaneously, the net force is the vector sum of all individual forces.
