why does the sun appears reddish while at rise and set?

Answer 1

According to Cloud R Us.com:

"The scattering of light can also be used to explain why the sky appears red at sunset. At this time, the sun’s rays have to pass through a much greater thickness of atmosphere than they do when the sun is high in the sky at midday. As a result, nearly all the blue light is scattered out by the particles in the air. Much more red light than blue lights is therefore reaching your eyes and the sun and sky appear red in colour. Clouds will also appear red or pink at sunset (or just after sunrise) because they are reflecting the red light of the sun."

Answer 2

The outcome is through a phenomena called Raleigh scattering. the ambience has debris of dirt floating round in it, as you would anticipate. the same old length of those debris is more beneficial or less a similar because the wavelength of blue uncomplicated. The upshot of that is that the blue uncomplicated passing through the ambience is scattered through those dirt debris, while different wavelengths, like orange, pink yellow passes immediately through. At daybreak and sundown, the suns uncomplicated arrives on the observer's eyes after passing through the ambience at a glancing perspective, and so passes through a lengthy way more beneficial air than if it were suggested rapidly above at midday. hence, more beneficial blue uncomplicated is scattered from it is course to the observer's eye, and so the sunlight looks more beneficial pink, orange and yellow. This also explains why the sky is blue everywhere. The blue is the scattered uncomplicated from the aforementioned dirt debris.

Answer 3

Extinction is stronger at shorter wavelengths, as shorter wavelengths interact more strongly with dust particles. Red light passes through gas and dust more easily than blue light. The more gas and dust between you and the source, the stronger the reddening. You observe this effect daily! When the sun and moon are near the horizon, you are viewing them through more atmosphere than when they are overhead. That is why the sun and moon look reddish when they rise and set. The reddening of starlight due to the interstellar extinction is known as interstellar reddening. Astronomers often used the terms extinction and reddening interchangeably.

Answer 4

The red hues of the sky at sunset and sunrise are caused by Mie Scattering, not Rayleigh Scattering. The colours of the sky throughout the day and at sunrise and sunset, are explained by the phenomena of both Rayleigh Scattering and Mie Scattering. The colour of the sky described by Rayleigh Scattering applies to the hues of blue, violet and green, not to the reds, oranges, peaches and purples of sunrise and sunset. Rayleigh Scattering is scattering of shorter wavelength light (e.g. blue & violet) by air atoms and molecules (not statistical variations in density of the Earth's atmosphere). The magnitude or strength of Rayleigh Scattering varies by the reciprocal of the wavelength raised to the fourth power, and hence does not explain the beautiful variations of reds, purples, oranges and peachy colours. The latter colours arise from Mie Scattering, low angle scattering of light off dust, soot, smoke and (ash) particles. Mie Scattering (producing the colours of sunset and sunrise) is beautifully recognizable down-wind of and after dust storms, forest fires and volcanic eruptions that inject large quantities of fine particulate matter into the atmosphere. A number of eruptions in recent times, such as those of Mount Pinatubo in 1991 and Krakatoa in 1883, have been sufficiently large to produce remarkable sunsets and sunrises all over the world. Sometimes just before sunrise or after sunset a green flash can be seen.

The sunset is often more brightly coloured than the sunrise, with the shades of red and orange being more vibrant. The atmosphere responds in a number of ways to exposure to the Sun during daylight hours. In particular, there tends to be more dust in the lower atmosphere at the end of the day than at the beginning. During the day, the Sun heats the surface of the Earth, lowering the relative humidity and increasing wind speed and turbulence, which serves to lift dust into the air. However, differences between sunrise and sunset may in some cases depend more on the geographical particulars of the location from which they are viewed. For example, on a west-facing coastline, sunset occurs over water while sunrise occurs over land.

Answer 5

because at sun rise and sunset light has cross more of the atmosphere

Answer 6

the atmosphere attenuates blue light more than red.

The sun pases thru more atmosphere when it's close to the horizon.
so it looks reddish

Answer 7

its because of the atmosphere, when the light comes down, the FREQUENCY changes (the wave lose energy) and u see it in a red color, but a few minuets later (in morning), the Canton changes and the wave can come don without energy losing,

Answer 8

The sunlight travels through more atmosphere and other colors are filtered.

Answer 9

Because of scattering of light

Answer 10

earth's atmospheric density
