At sunrise and sunset, the Sun's light must pass through a greater portion of the atmosphere to reach an observer than it does when the Sun is overhead. Blue light scatters effectively, which is why the sky appears blue during the day. But when the light has to pass through a thicker extent of air, the blue light scatters too much and is no longer visible. This causes red light to dominate in the evening and morning skies, because it scatters just the right amound.

because the distance of the sun relative to your position is longer at dusk and dawn, thus light from the sun must go through a great deal more of the atmosphere of the earth, and while going through it, the atmosphere caputures the higher frequency light, only leaving the red light to reach your position. And so the sky looks red.

The disk is actual a similar length for the duration of the day. it is an optical phantasm. The solar and the Moon the two look larger while low on the horizon considering the fact which you have foreground gadgets close by to allow you to benefit sizes. the colour of the solar ameliorations because of the ambience. in case you're taking a leaf by a prism, or onto a compact disc, you will discover a sort of colours that makes up white easy. a great form of those colours bend by different quantities, with blue easy bending perfect. pink easy infrequently bends in any respect. Yellow easy bends extra beneficial than pink yet no longer as much as blue (blue easy bends perfect!) - yellow is halfway between the two. while the solar is low on the horizon, lots of the different colours are bent faraway from our line of sight. All aside from the pink shade. as quickly as we actual see the solar low on the horizon, it has already long gone under the horizon! however the pink easy is bent plenty, that it is bent by the ambience around the Earth, and into your eyes.

The red hues of the sky at sunset and sunrise are caused by the Rayleigh scattering of blue light by statistical fluctuations in the density of Earth's atmosphere. This also causes the blue diffuse sky radiation. Relatively little red light is scattered in this way, and so the sky often takes on shades of red, orange and yellow. The color of a sunset may be enhanced by atmospheric phenomena such as clouds, smoke and smog produced by natural processes or human activity, and by ash from volcanic eruptions.

thats because the sun light is being filtered through a lot more of earths atmosphere and all the tiny particles create the shades we see. you can chech with discovery.ca
