Though still only in the prototype stage, this flat lens could one day be used on space telescopes, and perhaps even on ...

When a wave or light ray moves from one medium to another its speed changes. The direction of the ray may also change. This property of waves is called refraction and commonly occurs with light rays.

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

This video looks at the refraction of light and demonstrates how refraction can make the handle of a Pyrex jug seemingly disappear.

This film demonstrates the measurement of the speed of light in both air and water using experimental setups. The first experiment involves measuring the time it takes for light to travel a known ...
