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 ...

New York, NY—November 22, 2021—Over the past several decades, researchers have moved from using electric currents to manipulating light waves in the near-infrared range for telecommunications ...

Photons are odd little beasts. They can act like waves. They can act like particles. They are teeny tiny messengers of force. They are carriers of energy. If you're enjoying this article, consider ...

A simulated view of what Mars' night sky might look like at its poles. Credit: NASA/JPL-Caltech/Cornell Univ./Arizona State Univ.– E. W. Knutsen The night sky at Mars' poles looks nothing like our own ...

Due to how light travels, we can only see the most eye-popping details of space—like nebulas, supernovas, and black holes—with specialized telescopes. Electromagnetic Spectrum: the visible range ...

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 ...

This multipanel image show how different wavelengths of light can reveal different features of a cosmic object. On the left is a visible light image of the Whirlpool galaxy. The next image combines ...

IN continuation of our letter of October 29, we find that a reflexion grating does not show the bands so well as a quartz prism, because metals, e.g. silver-on-glass, do not reflect all this kind of ...

Researchers at the Indian Institute of Science (IISc) have fabricated a device to increase or “up-convert” the frequency of short infrared light to the visible range. Up-conversion of light has ...

Engineers have invented a breakthrough optical phase modulator that controls visible light -- without dimming it -- with the smallest footprint and lowest power consumption. New device will improve ...
