Recent Examples of refraction from the Web
The high refraction allows for the possibility of making light-manipulating structures on the surface of the sail that contribute to its reflectivity.
That generally means that those plans cover a comprehensive eye exam, including refraction, every year, as well as a pair of glasses or contact lenses.
The minerals in the rocks, plus refractions from the sun, create a range of colors under the water, from gold to deep blue.
The location high in the mountains of Chile is desirable because the air is so dry and thin here that atmospheric refraction, which obscures astronomers' views of the cosmos, is less of a hindrance than almost anywhere else on the planet.
The reflection/refraction of these materials also have to cover a broad range of wavelengths since, once the craft is moving fast enough, the incoming photons will be red-shifted.
The company makes nanocrystals — specks of zirconia a fraction of the width of a strand of hair — that can be added to polymers and coatings to improve the adhesiveness of specialty glues and improve refraction in LED lights.
Similar to sun dogs, lunar and solar halos belong to the family of ice halos, which are optical phenomena formed by the refraction of sun on hexagonal ice crystals suspended high up in the atmosphere, most commonly in cirrus clouds.
Changes in the speed of sound (or for that matter light) cause sound (or light) waves to bend, a phenomenon known as refraction.

Did You Know?
The root of refraction is seen in the notion that the path of a ray of light or wave of energy is "broken" when it is deflected or turned. The effects of refraction can be seen in a rainbow, which is formed when light rays passing into (and reflecting out of) water droplets are bent at different angles depending on their color, so that the light separates into bands of color. The amount of refraction depends on the angle and the type of matter; refraction can occur even when passing through different kinds of air. A mirage, such as you might see in the desert or over a patch of asphalt in the summer, occurs when light passing through warm air meets the very hot air near the surface; reflecting the sky, it often resembles a lake.
