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 ...

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

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

It is refraction that makes some objects appear to bend when they are viewed through water, like the straw shown here. If the light hits the surface of a glass block at an angle, this change in ...

A ray diagram showing refraction at the boundary between air and glass Refraction can cause optical illusions as the light waves appear to come from a different position to their actual source.

BISMARCK, N.D. (KFYR) - To create atmospheric optics we need two things: ice crystals in the air and a light source. All ...

The beam should bend back down. The physics is that of an upside-down mirage. In the tank, from top to bottom, the index of refraction is increasing, as in a mirage from the ground up. Shine the laser ...

THERE is a point in connection with the ordinary expositions of Fresnel's theory of double refraction to which, on account of its frequent occurrence, it is perhaps worth while to direct attention.

Minister of State for Health Narendra Shivaji Patel inaugurated a free refraction and dental check-up camp for the State Mantralaya employees and their family members at Vallabh Bhavan here on Monday.

The Huvitz HDR-9000 is a slim, curvilinear, wireless device that provides quiet, quick lens loading as well as accurate data ...
