  1. However, at sunset, light has further to travel through the atmosphere. The shorter wavelength blue light is scattered further, as the sunlight passes over a greater distance, and we see the longer wavelength yellow and red light. These effects are a cause of Rayleigh Scattering . Take our short survey.

    The Earth’s atmosphere is primarily made up of gas molecules, with oxygen comprising about 21% and nitrogen about 78%. In addition, water molecules in the form of droplets, ice crystals, and vapor, and particles such as dust, pollutants, and ash can be found in the atmosphere, which is denser closer to the Earth and thins out as the altitude increa...

    When sunlight strikes gas molecules, such as nitrogen and oxygen, light of longer wavelengths, like red, yellow, and orange, easily passes through, while light of shorter wavelengths, such as blue and violet, is absorbed and then scattered in all directions by the gas molecules. When you look up at the sky during the day, this scattered blue and vi...

    During sunsets and sunrises, when the Sun is closer to the horizon, sunlight has to travel through a longer distanceand more of the dense environment to reach an observer’s eye. Sunrise and sunset times in your city Due to Rayleigh scattering, most of the light of shorter wavelengths – the blue, violet, and green – are scattered away multiple times...

    The quality of the air that sunlight has to pass through also has an effect on the color of sunrises and sunsets. Dust particles and pollutants tend to tone down the colors in the skyas well as impede light from reaching the observer on the ground. Because of this, the sky takes on dull hues of red and yellow when the air is full of dust and pollut...

    Rayleigh scattering is also responsible for giving the Moon a reddish or orange hue during total lunar eclipses. The condition of the Earth's atmosphere, including the amount of pollution and dust from storms and volcanic eruptions, can affect the shade of red the Moon takes on during the eclipse. When's the next lunar eclipse? Topics: Astronomy, S...
