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 ...

Termed time refraction, this phenomenon causes the light pulse’s speed and frequency to keep changing as it moves. This is unlike spatial refraction, where the speed and directi ...

Light changes speed as it passes from one medium to another. This is called refraction. The frequency of light does not change as it refracts. The refractive index of a material is a measure of ...

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 unique feature has just occurred a couple of days before the spring equinox. We have the details on the extra daylight ...

When suitably cut and mounted between glass cover-slips, naphthalene crystals exhibit the phenomena of conical refraction in a very striking way, and enable their features to be critically examined.

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 ...

In addition to the objective refraction, the keratometer values and the pachymetry can be determined with precision in a matter of seconds with the PARK 1 ®. The integrated patient data ...
