How it works?

The **Principle of Superposition** states that when two or more waves travel through the same medium, the resultant value at any point is the vector sum of the individual waves at that point.

In this widget, **Wave A (Blue)** and **Wave B (Red)** superimpose to create the **Resultant Wave (Green)**. You can change the **Frequency** (pitch), **Amplitude** (loudness), and **Phase** (starting point) of Wave-A or Wave-B to observe effects like **constructive interference** and **destructive interference**.

To change any parameter by one unit, click on the slider and use the **Left** and **Right Arrow** keys.
