Rather than always traveling in a straight line, like you'd expect, light can change directions based on the medium its ...

Refraction close refractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ray changes direction when refracted by a lens.

The presence of water-ice in the debris disk around a young star could have helped facilitate the growth and development of ...

The quirks of light moving through gas are the cause of stellar twinkling, which can be a bane—and sometimes a boon—for astronomers ...

Northeast Ohio's weather conditions were just right early Tuesday morning to create some beautiful displays of light.

The idea was first hypothesized about 70 years ago. In a bizarre repercussion of Albert Einstein's Special Theory of ...

Among the most sought-after properties of metamaterials is the negative index of refraction of light and other radiation. Negative refraction is based on the equations developed in 1861 by Scottish ...

In a gradient, light bends towards the higher-index part, as the law of refraction predicts, or according to Fermat's principle. In a homogeneous medium (top and bottom), light does not bend. Mix up ...
