For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays - without the need for artificially manufactured metamaterials. Scientists have long ...

Well, OK, not exactly. A beam of light could pass through air all day long (as long as you have a layer of air 26 billion kilometers long) and not deviate a whit. But if the density of that air ...

IN preparing an elementary lecture on Light, intended to be given at the Taunton College School, I have had to consider how best to explain the somewhat abstruse principle of optical refraction. It is ...

The incident angle can be varied from 0 to 85 degrees. (In 5 degree increments using the +-5 buttons.) The index of refraction of the first medium is fixed at n=1.00. The index of refraction of the ...

NORFOLK, Va. ( WAVY) – When the war in Europe was over, another war, led by Jim Crow had no end in sight. The play, Refraction of Light is Jean Klein’s interpretation of 1940s life in Berkley for Jews ...

The Tentative Lists of States Parties are published by the World Heritage Centre at its website and/or in working documents in order to ensure transparency, access to information and to facilitate ...
