Recent Examples of refraction from the Web
Here observation gives way to imagination — the surface of Deimos, the outer Martian satellite, appears as parched clay — but these too relied on models and calculations of atmosphere, shadow and light refraction.
The first stage reduces lipids, which refract light a lot, and the second stage increases the refraction in the organs' surroundings, to better match it to the organ, allowing the light to pass cleanly through.
When that happens, the refraction scatters light, blocking out whatever’s underneath.
Microwave refraction has been used to detect breast cancers, and Elam and Ljungqvist think it could be applied in still more areas.
The London Fire Brigade said in 2015 that only 125 light refraction cases had been reported in the last five years — and not all of those fires were the result of doorknobs.

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.
