Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

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

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.

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

To investigate the reflection of light by different types of surface, and the refraction of light by different substances. Remove the block. Join the crosses to show the paths of the light rays ...

From beams of light shooting into the night sky to lightning in a snowstorm, Big Sky Country is full of winter weather that ...
