Researchers have developed experimental contact lenses that use nanoparticles to convert the invisible wavelengths of ...

These bands selectively remove portions of the light spectrum, creating gaps in the light available for photosynthesis. Previous research by Maayke Stomp and Prof. Huisman demonstrated that these ...

What we call white light is just that midway point where the radiation peak is in the middle of the visible spectrum. The reason our eyes are sensitive to this part of the spectrum is simply ...

Abstract: Precise luminance evaluation of light pollution requires expensive and time-consuming measurement devices such as hyperspectral imaging cameras and imaging luminance-meters, which are also ...

Hopkins, a 2600-meter (8600 foot) tall mountain in the Santa Rita Mountains ... CfA developed a suite of instruments both to create images and to analyze the spectrum of light from astronomical ...

Previous generations spent much more time outdoors bathed by a natural light spectrum that includes ultraviolet, deep violet, the other colors of the visible light spectrum, and infrared wavelengths.

Let's get into the ~science~: Blue light is part of the visible light spectrum, which is what the human eye can see, explains Dr. Hogan. The visible light spectrum ranges from wavelengths of ~400 ...

Light meters are a godsend for photographers, as they tell them how much light is either falling onto the subject of the shot or reflecting back at the camera. Having that information helps ...

Just like a traditional light meter, you can measure the difference or ratio between ... You can measure illuminance in either lux of foot-candles. This is also a Spectrum Mode where Evaluate the ...
