The visible spectrum is the band of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light (or simply light).
The blue sky spectrum contains light at all visible wavelengths with a broad maximum around 450–485 nm, the wavelengths of the color blue. Diffuse sky radiation is solar radiation reaching the Earth's surface after having been scattered from the direct solar beam by molecules or particulates in the atmosphere. It is also called sky radiation ...
It takes all the colors of the rainbow for us to see it that way. It happens because of something called the Rayleigh effect, or Rayleigh scattering, named after a British scientist who first ...
Magenta is variously defined as a purplish-red, reddish-purple, or a mauvish–crimson color. On color wheels of the RGB and CMY color models, it is located midway between red and blue, opposite green. Complements of magenta are evoked by light having a spectrum dominated by energy with a wavelength of roughly 500–530 nm.
The night sky in Wisconsin glows with the Northern Lights as a geomagnetic storm brings vibrant pink and green colors to a majority of the northern states. / Credit: Ross Harried/NurPhoto via ...
The northern lights should be visible again in Ohio on Sunday night. A sky full of pink shades with ribbons of green light should be able to be seen Sunday night and into Monday morning after ...
The color of a cloud, as seen from the Earth, tells much about what is going on inside the cloud. Dense deep tropospheric clouds exhibit a high reflectance (70% to 95%) throughout the visible spectrum.
The pair will be visible for almost three hours after sunset, offering a great view once the sun has set or the sky is fully dark. Related: The Strongest Meteor Shower of the Year Is Currently ...
