The red colour in the sky at sunset (and sunrise) is due to an effect called Rayleigh scattering. There is a similar form of scattering called Mie scattering which is responsible for the white colour of clouds.
Particles in our atmosphere that are approximately the same size as the wavelength of visible light cause the white light from the sun to scatter and split into individual components. Oxygen and Nitrogen (the main components of our atmosphere) scatter violet and blue light due to their small size. This is why the sky appears to be blue in the day time, especially at midday when the Sun is closest to us.
During sunrise and sunset the distance that the light has to travel from the Sun to an observer is at its greatest. This means the a large amount of blue and violet light has been scattered so the light that is recieved by an observer is mostly of a longer wavelength and therefore appears to be read.

sunsets are red in colour because of scattering of light. As the distance of the sun from earth increases than in the mid afternoon all the other colours would have scattered except red so sunsets are red in colour.

Sunsets are red because you arent catching as direct of a sun's light ray. the weaker they are, the more red they are and then eventually they aren't visible. You're catching almost a reflection of the sun off the atmosphere as the earth turns into your way.

From all the impurities in out air...you see the sun at a sunset, through the most of our atmosphere...

The atmosphere bends the light the sun is shining on at the horizon and makes the sun look red/orange

Red has a larger wavelength, it travels deeper and farther. Thats why when you dont see the sun, you can see the red of its spectrum.It comes first or goes last. Know you also know why the danger lights are RED :)

Air molecules and dust particles in the air scatter more blue light than red light, so only the red light makes it to your eyes.

hi gokul.
sun sets in red colour due to total internal reflection.and red colour has high scaterring capability...
