Blue skies may seem to appear every day, but have you ever stopped to think why this happens? The answer lies within light’s path through our atmosphere. When sunlight reaches our atmosphere, it rebounds off gas molecules and scatters in all directions – blue wavelengths tend to disperse more easily than other colors. Rayleigh Scattering…
As sunlight passes through the atmosphere it gets refracted or scattered by air molecules; light nearer the blue end of the spectrum tends to get scattered more than other colors, giving a blue hue to the sky. At sunrise and sunset, light traveling through longer distances in the atmosphere becomes less scattered, allowing more red…
As sunlight passes through our atmosphere, its energy becomes scattered in various directions. Shorter wavelength light waves such as blue tend to disperse more widely than their red counterparts. John Tyndall and later Lord Rayleigh helped reveal why the sky appears blue. What is the colour of the sky? Rayleigh scattering is responsible for creating…
Have you noticed how the sky is an endless sea of blue? Closer to the sun, its hue becomes lighter while moving further from it. Light travelling through Earth’s atmosphere collides with molecules and particles such as oxygen and nitrogen, scattering light in various directions. Shorter wavelengths like blue are scattered more than longer ones…
As sunlight enters Earth’s atmosphere, it interacts with dust particles, water droplets and gas molecules in its path to scatter all colours of light – though blue light tends to be dispersed more widely due to having shorter wavelengths; thus creating the characteristic blue hue we associate with skies. Learn about sky-blue such as its…
Space can be an unforgiving environment that challenges spacecraft to operate reliably for extended missions. Engineers develop power systems with redundancy in mind to reduce system failure risk that might jeopardize a mission. The main EPS inverters utilize 30 V DC from the maneuver booster regulator and convert it to the 2.4 kHz square wave…
As soon as sunlight hits our atmosphere, its rays scatter, creating what is known as Rayleigh scattering, named for 19th century physicist Lord Rayleigh. Shorter wavelength light such as blue and violet scatters more than long wavelength light; hence why our sky appears bluer. This phenomenon was named for Lord Rayleigh’s 19th century experiment on…
Quora does not moderate any questions asked to it, unlike Wikipedia where volunteers continually proof and correct articles in order to create a reliable information source. Quora simply lacks this feature. Unfairly placing value on questions at the expense of answer authors who spend hours crafting detailed replies would be silly. Quora should devise a…
Have you ever found yourself looking up on a sunny day and wondering why the sky appears blue? Turns out there’s an excellent explanation! The color of the sky is determined by how sunlight interacts with our atmosphere. Sunlight passes through air molecules, scattering in all directions with blue hues being more heavily dispersed than…
