Scientists have found a way to achieve negative refraction—where light bends the "wrong" way—using carefully arranged atomic ...

For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays - without the ...

Light bends when travelling through a concentration ... In the tank, from top to bottom, the index of refraction is increasing, as in a mirage from the ground up. Shine the laser pointer horizontally ...

A mirage is caused by refraction of light rays that travel through air layers with uneven temperatures. The high school Earth Science Group members confirmed through their experiment that a mirage ...

When a wave or light ray moves from one medium to another its speed changes. The direction of the ray may also change. This property of waves is called refraction and commonly occurs with light rays.

Scientists have long sought to control light in ways that appear to defy the laws of Nature. Negative refraction -- a phenomenon where light bends in the opposite direction to its usual behavior ...
