why sun seems red when sunrise or sunset in morning and evening?

Answer 1

The atmosphere tends to absorb higher wavelengths.
The more atmosphere the light has to go through, the less higher
wavelengths get through, so you are left with lower wave lenghts
(red).

When the sun is coming to you at its lowest angle (sunrise, sunset)
its light is going through the most atmosphere.

Note that the effect is much less pronounced on high mountains because
it is going through less atmosphere.

Answer 2

At sunrise and sunset the rays from the sun have to travel a larger part of the atmosphere than at noon. Therefore most of the blue light is scattered away and only the red light which is least scattered reaches the observer. Hence, sun appears reddish at sunrise and sunset

Answer 3

At Sunrise & Sunset the Sun is at the farthest point from the earth. Only the Red light which is having the maximum wave length is able to reach our eyes & we can see the Sun as RED during Sunrise & Sunset.

Answer 4

At sunset or sunrise, when the sun appears very low in the sky, the light has to pass through more of the air ("thicker" air) closer to the earth's surface.

While more blue light is flung out, almost all of the red and yellow light remains, resulting in a tremendous burst of color. The red, orange and yellow hues that thrill sunset viewers progress more or less in a straight line directly from the sun to human eyes.

Answer 5

The ray of sun consist of seven colour called VIBGYOR. When sun rays passes through water droplets it behave like a prisem and split into seven colour,and have different wave length,and we see the combination of orange and red which are the less wave length so we see reddish colour during sunrise and sunset.

Answer 6

Its easy in mornings or evenings the light rays from the sun has to travel a long distance than it does at noon so the atmosphere absorbs all the blue light and difracts only the red end of the spectrum so the sky and the sun appears red in dawn and dusk

Answer 7

Because the sunlight has to pass through more air during those times, and the blue wavelength light gets scattered too much, while the longer red rays are able to be seen.

During the day, there isn't as much air to pass through, so the blue rays are what we see in the sky.

Incidentally, if you were on the moon, the sky would be black even with the sun in full view, because there's no air on the moon to scatter the light.

Answer 8

It is because of the diffraction of sunlight by dust particles in the atmospheric layer of earth. Since red light has the largest wave length in light spectra it diffracted more and hence during sunrise sun seems red

Answer 9

The color of the sky at sunrise and sunset is explained by the phenomenon of Rayleigh scattering.

Rayleigh scattering (named after Lord Rayleigh) is the scattering of light, or other electromagnetic radiation, by particles much smaller than the wavelength of the light. It occurs when light travels in transparent solids and liquids, but is most prominently seen in gases. Rayleigh scattering of sunlight by the atmosphere is the main reason light from the sky is blue.

Answer 10

this is due to the fact that during sunrise and sunset we do not receive direct rays of sun .rather an oblique rays that travels through thick blanket of air ,dust particles and get deffracted there by appearing redder to us.
