Scientists have demonstrated how to manipulate light by using time-varying media in the form of specialized nanomaterials.

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 ...

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.

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 ...

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 ...
