SUMMARY
The problem involves calculating the horizontal distance from a lighthouse to a shipwreck based on the angle of incidence of light. The lighthouse is 55 meters above sea level, and the beam strikes the water at an angle of 63 degrees, illuminating a shipwreck located 17 meters deep. Using the tangent function, the horizontal distance to the point directly below the light source is calculated as 110 meters. After applying Snell's Law, the angle of refraction is determined to be 42 degrees, leading to an additional distance of 15 meters, resulting in a total horizontal distance of 125 meters from the lighthouse to the shipwreck.
