GRAND RAPIDS — Every day we see and use light for numerous daily functions, but did you know you can actually bend light? Its called refraction and our experiment today is going to show you how its ...

Nearly a decade after getting waves of light to bend backward, physicists have done the same with electrons. Electrons coursing through a sheet of carbon atoms exhibited negative refraction, bending ...

Well, OK, not exactly. A beam of light could pass through air all day long (as long as you have a layer of air 26 billion kilometers long) and not deviate a whit. But if the density of that air ...

When it comes to light, certain types of fabricated materials behave in a radically different manner from ordinary materials like water and glass: they have negative refractive indices, so that light ...

The first law of refraction states that the incident rays, refracted rays, and the normal to the interface at the point of incidence, all lie in the same plane. The ratio of the sine of the angle of ...

Step into the hidden science lab in your kitchen with five easy experiments that explain refraction, surface tension, ...

Sometimes when you look into a swimming pool it’s difficult to tell how deep the water actually is. If you grab something long, like a stick, you can use it to test the depth of the water. Upon ...

Invisibility used to be the stuff of comic books and Harry Potter novels. But this week, scientists from UC Berkeley have emerged with two new invisibility-producing “metamaterials,” engineered ...
