Visible light, infrared, ultraviolet, X-rays, gamma rays... These terms are not unfamiliar to us. Together, they form the ...

At the core of the breakthrough is an optical parametric oscillator (OPO), a resonator that converts incoming laser light ...

One of the landmark discoveries of 19 th century physics was the realisation that electricity, magnetism and light are all connected. Experiments had already shown that the movement of electrical ...

How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...

Focused laser-like light that covers a wide range of frequencies is highly desirable for many scientific studies and for many ...

In a breakthrough for next-generation technologies, scientists have learned how to precisely control the behavior of tiny ...

When you look at the night sky, do you ever wonder what's going on out there? On a clear night with a dark sky, if moonlight doesn't wash it out, sometimes you can see the arc of the Milky Way. The ...

Did you know you've been cooking your food with light? Most of us have a microwave oven in our kitchens, and that's exactly what they do. When you press start, a device called a magnetron emits a ...

EGLIN AFB — Eglin Air Force Base is the home, at least for now, of a first-of-its-kind Air Force wing working in the electromagnetic spectrum, which stretches from radio waves to visible light and ...

This is what fun looks like for a particular set of theoretical chemists driven to solve extremely difficult problems: Deciding whether the electromagnetic fields in molecular polaritons should be ...
