For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays - without the need for artificially manufactured metamaterials. Scientists have long ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Adam Sherwinski teaches ciLiving host, Jaclyn Friedlander about light refraction. Watch how light bends when it passes through ...

Scientists have created a new class of laser beam that appears to violate long-held laws of light physics. These new beams, which the team calls “spacetime wave packets,” follow different rules of ...

Microscopic crystals in tantalum disulfide have a starring role in what could become a hit for 3D displays, virtual reality and even self-driving vehicles. Microscopic crystals in tantalum disulfide ...

What color is the coronavirus? Conventional optical microscopes are unable to generate high-resolution, colored images of viruses and bacteria. Expensive equipment is used to view them in a more real ...

IN preparing an elementary lecture on Light, intended to be given at the Taunton College School, I have had to consider how best to explain the somewhat abstruse principle of optical refraction. It is ...
