Principle of Superposition

Principle of Superposition

### Formula

$$y=y_1+y_2$$

### Terminologies

- y → Resultant displacement.

- y1, y2 → Individual displacements.

### Conditions / Special Cases

Constructive interference:

$$y_{max}=y_1+y_2$$

Destructive interference:

$$y_{min}=|y_1-y_2|$$

### Usage

- Used in interference problems.
