Light is refracted when it enters a material like water or glass. Depending on the density of the material, light will reduce in speed as it travels through, causing it to change direction. Ray ...

From ribosomes assembling proteins to viruses attacking cells, the main dramas in biology happen on a scale that is, tantalizingly, just one order of magnitude below the resolution of the best optical ...

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 ...

Physicists in the US have made the first ultrathin flat lens. Thanks to its flatness, the device eliminates optical aberrations that occur in conventional lenses with spherical surfaces. As a result, ...

The first law of refraction states that the incident rays, refracted rays, and the normal to the interface at the point of incidence, all lie in the same plane. The ratio of the sine of the angle of ...

A new laser under development by BAE Systems could boost a high-flying airplane's ability to spot targets on the ground, creating a temporary floating "lens" in midair that magnifies objects. The same ...
