The paper shows that the striking phenomena of short-wave radio transmission (i. e., below 60 meters) can be quantitatively accounted for on a simnple electron refraction theory in which the effect of ...

The green flash is a rare, brief optical event of green, yellow, and sometimes blue that colors the horizon, occurring at sunrise or sunset most often in the western U.S. Refraction and dispersion ...

The green flash is caused by refraction and dispersion. Refraction is the bending of light, while dispersion scatters it. “Earth's atmosphere is not uniform – not only is it curved, but its density ...

Haze-induced image degradation in outdoor scenes, caused by atmospheric scattering and absorption, poses significant challenges for applications such as surveillance, autonomous navigation, and remote ...

According to Environment Canada Meteorologist Matt Loney, no two sunsets are the same, similar to snowflakes. Mother Nature's ...

A "blood moon" rose over the UK during a partial lunar eclipse on March 14. The eclipse became visible for many across the world as the Moon travelled through the Earth's shadow. This type of eclipse ...

When the wavelengths of light hit the surface of the Moon, they can make it appear red. If you missed the partial lunar eclipse earlier this year, you may want to keep an eye towards the night sky ...
