The principle of superposition in waves states that when two or more waves overlap in space, the resulting wave at any point is the sum of the individual wave functions at that point. This principle is foundational in wave theory and applies to various types of waves, such as sound waves, light waves, and water waves.

When waves meet, they do not alter each other's individual properties; instead, they can coexist simultaneously. For example, if one wave has a peak at a certain point and another wave has a trough at the same point, the total displacement at that point will be the algebraic sum of the two displacements. This results in constructive interference when waves are in phase, or destructive interference when they are out of phase.

The superposition principle allows for a wide range of phenomena, including beats in sound waves and interference patterns in light waves. Understanding this principle is crucial for analyzing complex wave behavior in various physical contexts.
