Question: User: Scene 7: Scientific Evidence & Lesson Summary Visual Prompt for AI Video Generator: Prompt: Split-screen historical and modern physics animation[cite: 15]. On the left: Thomas Young's classic double-slit wave interference pattern[cite: 15]. On the right: Sound wave nodes and antinodes glowing dynamically[cite: 15]. Animated concluding summary card displays: "Sound Cancellation proves Sound is a Wave!"[cite: 15] and "Path Difference Δd determines Loudness or Silence"[cite: 15]. Dynamic 3D particle lighting effects. English Voiceover & Text: Voiceover: "Points of total silence prove that sound travels as a wave[cite: 15]—two combining disturbances yielding zero effect cannot be explained by simple particles[cite: 15]! Master path differences, master wave interference!"
