In 3-4 sentences, explain the principle of superposition. State any key formula.

The principle of superposition states that when two or more waves overlap in space, the resulting displacement at any point is the algebraic sum of the individual displacements from each wave. This applies to any system where the governing equations are linear, such as electromagnetic waves, sound waves, and quantum mechanical wave functions. The key formula is: **ψ_total = ψ₁ + ψ₂ + ψ₃ + ... + ψₙ** where ψ represents the wave function or displacement, and the subscripts denote individual waves. This principle allows complex wave patterns to be analyzed as combinations of simpler waves.
