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 ...

A team of engineers built a system that lets people to see colors in the infrared spectrum — as long as they’re looking through a camera lens. The team says that the device can be used to image gases ...

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.

In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, propagating through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves ...

Researchers in Quebec, Canda, have developed the first fiber laser that can produce femtosecond pulses in the visible range of the electromagnetic spectrum. Fiber lasers producing ultrashort, bright ...
