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 new type of versatile economical photocatalyst that harnesses the visible portion of the sunlight spectrum has been developed by researchers from the University of Johannesburg. It is simple to ...

Ultraviolet (UV) light has higher energy photons than visible light and, thus, has more applications. Researchers have now developed a brilliant innovation -- a solid-state material that can stably ...

Spring is galaxy season for many amateur astronomers. However, when looking through an eyepiece instead of a camera for astrophotography, you might think of this as the season of pale gray smudges ...

Solar water splitting is one of the most direct ways to produce green hydrogen using sunlight. However, most photocatalysts ...

You’ve very well known by now the transition of the colors you see as the sunrises or sets. It can be a range of vivid colors ...

The experimental setup shown here incorporates on-chip optical parametric oscillator (OPO) technology to generate a frequency comb of laser-like light covering a wide range of frequencies with very ...
