WebIf light enters a medium from another substance at a 90-degree angle, it does not refract and passes right through. Astronomical Refraction When the light of a celestial object, like the Sun, enters the Earth's atmosphere from space, the resulting refraction is known as astronomical refraction or atmospheric refraction. WebMay 5, 2016 · When light that is traveling through the air hits water, some of the light is reflected off the water. The rest of the light passes through the water but it bends (or refracts) as it enters the water.
