Question: User: Scene 3: The Path Difference Rule & Mathematical FormulaVisual Prompt for AI Video Generator:Prompt: Futuristic glass HUD interface with animated physics equations on a dark background . A ruler diagram shows path difference Δd = |S1P - S2P| . The equation for Constructive Interference animates in glowing blue text: Δd = n * λ (n = 0, 1, 2...) . The equation for Destructive Interference animates in glowing red text: Δd = (n + 0.5) * λ . Below, a scale counts path difference in half-wavelengths (λ/2): even numbers yield loud spots, odd numbers yield quiet spots .English Voiceover & Text:Voiceover: "The key to interference is Path Difference, Δd[cite: 15]! If the path difference equals a whole number of wavelengths, n times lambda, waves arrive in phase, causing constructive interference[cite: 15]. If it equals an odd number of half-wavelengths, waves cancel, producing total silence[cite: 15]!"
