Researchers have used a 350-year-old theorem to better understand the strange nature of light. The team took a theorem used for describing pendulums and substituted the brightness of light in for what ...

Chapter 1: What is light? There was a mystery in that assuming either light is a wave or a particle would result in contradictory phenomena, but today quantum electrodynamics is recognized as the most ...

Physicists use a 350-year-old theorem that explains the workings of pendulums and planets to reveal new properties of light waves. Since the 17th century, when Isaac Newton and Christiaan Huygens ...

In 1845, physicist Michael Faraday provided the first direct evidence that electromagnetism and light are related. Now, it turns out that this connection is even stronger than Faraday imagined. In his ...

Physicists have developed a lens with 'magic' properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light. Lenses are the most widely used ...

A material coating, whose light refraction properties can be precisely switched between different states, has been developed by an interdisciplinary research team from the Chemistry and Physics ...
