Question: User: Scene 4: Solved Numerical Example - Quincke's Tube Experiment Visual Prompt for AI Video Generator: Prompt: 3D precision apparatus model of Quincke's Tube[cite: 15]. Sound enters at point P and splits into two U-shaped tube branches before recombining at outlet Q[cite: 15]. Branch B slides outward smoothly by distance x = 8.5 cm, increasing total path difference by 2x = 17 cm (0.17 m)[cite: 15]. At outlet Q, the sound intensity drops to its first minimum (silence)[cite: 15]. Animated equation overlay calculates step-by-step: λ/2 = 0.17 m → λ = 0.34 m[cite: 15]. Frequency calculation: f = v / λ = 340 / 0.34 = 1000 Hz[cite: 15]. Numbers light up in neon gold. English Voiceover & Text: Voiceover: "Let's solve Example 1 using Quincke's Tube! Sliding the tube out by 8.5 cm adds double that distance—17 cm—to the path length[cite: 15]. Since the first minimum occurs at half a wavelength, lambda equals 0.34 meters[cite: 15]! With sound speed at 340 m/s, the frequency calculates to 1000 Hertz[cite: 15]!"
