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 can only be seen by looking into the mirror. If a surface is rough, diffuse reflection happens. Instead of forming an image, the reflected light is scattered in all directions. This may cause a ...
