Light refraction is caused when the ray of light travels through different mediums and slows down or speeds up. In the case of this stick in the pool, water and air are two different mediums.

THERE is in Upper Thibet a plateau called the “Kyan Chu Plain,” on which phenomena of mirage are frequently seen. The plain is at a height varyingfrom 15,000 to 16,000 feet. A cold wind comes ...

Scientists have created a new class of laser beam that appears to violate long-held laws of light physics. Known as “spacetime wave packets,” these lasers follow different rules of refraction ...

Refraction occurs when light changes direction as it passes, e.g., from air into water or glass. Negative refraction, however, is a counterintuitive effect where light in a medium bends in the ...
