Waves Superposition – Interactive Learning

The picture showing red and blue wave superimposed onto each other whereas green wave is the resultant wave as result of superposition of red and blue wave.

Sine Wave Superposition — A + B → Resultant 🎵 Waves Superposition Learning 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)** … Read more
