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

The change in direction of a beam of light as it travels from one material to another is called refraction. The normal is a construction line drawn at right angles to the surface of the glass block.

It is then refracted away from the normal at the boundary between glass and air as it leaves the prism.

Weather can be as unpredictable as it is fascinating. From the gentle patter of rain to the ferocity of thunderstorms, the ...

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 demonstrates how light travels in straight lines, how mirrors can reflect images, and how different surfaces affect light behavior. The film also explains how lenses work to focus images, ...
