Pulse Superposition

Watch two pulses traveling toward each other overlap, and see constructive and destructive interference happen in real time.

Wave Superposition (Interference)

Amplitude A (y₁) 100 px

Amplitude B (y₂) 60 px

Pulse Width (w) 50 px

Wave Speed 4

Wave A (y₁) —

Wave B (y₂) —

Max Overlap (y) —

Interference —

Principle of Superposition

y = y₁ + y₂

When pulses completely overlap:

y = —

Resultant Amplitude —
