Skyline what is the blue light

When light hits a gas molecule, some of it may get absorbed. After awhile, the molecule radiates releases, or gives off the light in a different direction. The color that is radiated is the same color that was absorbed.

The different colors of light are affected differently. All of the colors can be absorbed. But the higher frequencies blues are absorbed more often than the lower frequencies reds. This process is called Rayleigh scattering. It is named after Lord John Rayleigh, an English physicist, who first described it in the 's. The blue color of the sky is due to Rayleigh scattering.

As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air. However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions.

It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue. As you look closer to the horizon, the sky appears much paler in color.

To reach you, the scattered blue light must pass through more air. Some of it gets scattered away again in other directions. Your commute. Your news.

In the RGB color wheel of additive colors, cyan is midway between blue and green. The water absorbs the color red from the sunlight, leaving a greenish-blue color.

What colors can we not see? Red-green and yellow-blue are the so-called "forbidden colors. The limitation results from the way we perceive color in the first place.

What color is the grass? Is the sun black? The Sun, with an effective temperature of approximately K, is an approximate black body with an emission spectrum peaked in the central, yellow-green part of the visible spectrum, but with significant power in the ultraviolet as well. What is the Colour of sky at night? Why do I see red? We perceive only the reflected colors.

The surface of the apple is reflecting the wavelengths we see as red and absorbing all the rest. The sky appears red because small particles of dust, pollution, or other aerosols also scatter blue light, leaving more purely red and yellow light to go through the atmosphere. For example, Mars has a very thin atmosphere made mostly of carbon dioxide and filled with fine dust particles. During the daytime, the Martian sky takes on an orange or reddish color. But as the Sun sets, the sky around the Sun begins to take on a blue-gray tone.

The top image shows the orange-colored Martian sky during the daytime and the bottom image shows the blue-tinted sky at sunset.

Our World: Sunsets and Atmospheres. Why Is the Sky Blue? The Short Answer:. Blue light is scattered more than the other colors because it travels as shorter, smaller waves.
