SUMMARY
The discussion focuses on calculating the angle at which light exits water when a diver shines a flashlight upward at a 23.0° angle to the vertical. The correct approach involves applying Snell's Law, which states that n1 * sin(θ1) = n2 * sin(θ2). Here, n1 is the index of refraction of water (1.333), θ1 is the angle of incidence (23.0°), and n2 is the index of refraction of air (1). The calculation leads to determining the angle of refraction (θ2) as the light exits the water.
