Why SUN appears red in dawn?

Answer 1

Why SUN appears red in dawn? (and dusk)

This is the time when the sun's light travels through most atmosphere to reach us. The small particles of dust scatter some of the light and most of the light scattered is blue light. As the blue light gets scattered out of the original white light the light that reaches us has a bredominance of red light and so the sun appears red.

This also explains why the sky appears blue during the day as we see much of this scattered light coming at us from all directions. It also explains why when we see the sun through smoke it appears very red as well and why we see great sunsets after days with a great deal of haze or after some event such as a huge volcanic eruption somewhere on the earth gives us a long sequence of beautiful sunsets (and sunrises) as the eruption of Mt Pinatubo in the Philipines did in the 1980s

Answer 2

when the sun is overhead (in the noon).it's rays have to cross less
distance in the earths atmosphere .so the scattering the rays is less but at dawn the suns rays have to cross larger distance in earths atmosphere,more light is scattered.the red wavelength is least scattered and it reaches the earth making the the sun appear red

Answer 3

The colors of the sky, throughout the day and at sunrise and sunset, are explained by the phenomenona of both Rayleigh Scattering and Mie Scattering. The red hues of the sky at sunset and sunrise are caused by Mie Scattering, not Rayleigh Scattering. The hues of blue, violet, and green in the sky are due to Rayleigh Scattering. 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 colors. The latter colors arise from Mie Scattering, low angle scattering of light off of dust, soot, smoke, and (ash), particles. Mie Scattering, (producing the colors 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.

Answer 4

Tis due to scattering of other wavelengths of the visible solar spectrum.red light is of higher wavelength n is transmitted rather than being scattered by the air molecules.refer to Rayleigh's scattering phenomenon.

Answer 5

Because you're looking through more atmosphere at the horizen than overhead, and the more atmosphere you have, the more light is scattered. Shorter (bluer) wavelengths are more scattered, so only the redder ones make it through at the horizen - but more yellow makes it through less atmosphere overhead.

Answer 6

it extremely is to do with the diffraction of the sunlight's rays as they enter the ambience. it extremely is the comparable as while easy enters a prism. only at sunrise and nightfall does the sunlight make the perspective with the Earth mandatory to chop up the sunshine interior the main astounding way for this shade to be seen.

Answer 7

its because scattering of light is inversely prportional to 4th power of the wavelength
red colour has the largest wavelength so it scattrs least and is occupied at one place

Answer 8

Hi. Because most of the blue has been filtered out.

Answer 9

due to REFLECTIONISM
