Rayleigh scattering causes the blue color of the daytime sky and the reddening of the Sun at sunset. Rayleigh scattering (/ ˈ r eɪ l i / RAY-lee) is the scattering or deflection of light, or other electromagnetic radiation, by particles with a size much smaller than the wavelength of the radiation.
It might seem like a simple question. But the science behind a blue sky isn't that easy. For starters, it involves something called the Rayleigh effect, or Rayleigh scattering. But that same ...
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 ...
Of the Blue Colour of the Sky is the third studio album by American rock band OK Go.It was released on January 12, 2010, on Capitol Records in the US and EMI in the UK, and re-released on the band's independent label Paracadute Records on April 1.
Maimonides claimed that this blue was the colour of "the clear noonday sky"; Rashi, the colour of the evening sky. [88] According to several rabbinic sages, blue is the colour of God's Glory. [ 89 ] Staring at this colour aids in mediation, bringing us a glimpse of the "pavement of sapphire, like the very sky for purity", which is a likeness of ...
Deep sky blue is an azure-cyan colour associated with deep shade of sky blue. Deep sky blue is a web colour. This is the colour on the colour wheel (RGB/HSV colour wheel) halfway between azure and cyan. [34] The colour name deep sky blue came into use with the formulization of the X11 colour names over 1985–1989.
The color of light from the sky is a result of Rayleigh scattering of sunlight, which results in a perceived blue color. On a sunny day, Rayleigh scattering gives the sky a blue gradient, darkest around the zenith and brightest near the horizon.
The brightness and color of the sky vary greatly over the course of a day, and the primary cause of these properties differs as well. When the Sun is well above the horizon , direct scattering of sunlight ( Rayleigh scattering ) is the overwhelmingly dominant source of light.
