Question: User: Scene 5: Antiphase Sources Comparison Visual Prompt for AI Video Generator: Prompt: Split-screen comparison animation[cite: 15]. Left Side: In-Phase sources producing constructive interference at center line Δd = 0[cite: 15]. Right Side: Antiphase sources (180 degrees out of phase, one moves up as the other moves down)[cite: 15]. The center line now becomes a completely dark, silent nodal line (Destructive Interference) with amplitude 0 cm[cite: 15]. Text overlay dynamically swaps formulas: "Antiphase Swap: Δd = (n + 0.5)*λ becomes Constructive, Δd = n*λ becomes Destructive"[cite: 15]. English Voiceover & Text: Voiceover: "If sources vibrate in antiphase—180 degrees out of step—the conditions reverse completely[cite: 15]! Equal path lengths now create destructive cancellation instead of reinforcement[cite: 15]."
