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 ...

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 ...

In a new study published in Science, researchers have developed a new method for detecting infrared light by changing its frequency to a corresponding frequency in the range of visible light.

Scientists have built the first optical frequency comb -- a tool for precisely measuring different frequencies of visible light -- that actually looks like a comb. Finally, an optical frequency comb ...

Light is an electromagnetic wave: it consists of oscillating electric and magnetic fields propagating through space. Every wave is characterized by its frequency, which refers to the number of ...

Integrated photonics is a rapidly-evolving industry sector, with infrared spectrum applications including high-speed 5G networks, biosensors on chip, and driverless cars. Researchers are now exploring ...

BENGALURU: 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. The human eye can only ...

Visible light is a form of electromagnetic (EM) radiation, as are radio waves, infrared radiation, ultraviolet radiation, X-rays and microwaves. Generally, visible light is defined as the wavelengths ...
