As we delve into The Physics Classroom Tutorial's Reflection and Refraction units, it becomes evident that sight relies on a fundamental process: light emanating from an object travels directly to our eyes when we line up a direct shot at that object. Conversely, we see a precise image of an object because light from that very same object is cleverly diverted - whether through reflection off a mirror or by passing straight through transparent material. And lo and behold! As this diverted light journeys toward our peepers at the precise image location of the original object, a dead ringer of that object emerges, created through the sheer power of convergence - or, indeed, divergence of said light from this point. Whether we're working with reflection or refraction scenarios, trusty old ray diagrams serve as beacons for tracing light's route from object to peeper.
