Discover how converging lenses create real and virtual images in this clear and engaging physics tutorial. This video breaks down the principles of refraction, focal points, and image formation, using ...

The negative refraction of electrons in graphene has been seen for the first time in experiments done by physicists in the US. The work represents an important advance in the fabrication of graphene ...

For the first time, physicists have devised a way to make visible light travel in the opposite direction that it normally bends when passing from one material to another, like from air through water ...

Physicists are involved in an unusually heated debate over the reality of a new kind of refraction and about the possibility of making perfect lenses. Edwin Cartlidge reports. If you think science is ...

We’ve all seen reflection used in photography—like when a lake doubles as a mirror to the sky. For this week’s Shooting Challenge, we’re going a step more complicated and using the principles of ...
