Question: User: Scene 1: The Water Tank Experiment & Refraction PhenomenaVisual Prompt for AI Video Generator:Prompt: A photorealistic 3D cinematic shot inside a dark laboratory. A narrow red laser beam shoots upward through a transparent glass tank filled with water (n1 = 1.33) toward the water-air interface (n2 = 1.00) . At a small incident angle i = 30°, the laser ray splits at the surface: a weak reflected ray bounces back into the water, while a bright refracted ray exits into the air bending away from the normal line at an angle r = 41.8° . Crisp optical physics simulation, 4K resolution, dynamic camera movement.English Voiceover & Text:Voiceover: "When light travels from water into air at a small angle, part of it refracts into the air while a faint beam reflects back. As light enters a less optically dense medium, it speeds up and bends away from the normal. But what happens as we widen the angle?"
