Why does the colour of the sky change with the time of the day ?

Answer 1

The light that reaches the earth from sun is only White light..i.e. mixture of all possible colours, but once the light enters the atmosphere, it undergoes scattering by the particles present in the atmosphere and this scattered light appears in the blue region(short wave radiation) of the white light and hence we see the blue colour.

But during sun rise and sunset, the light travels in the so long that much of the blue and even yellow light is scattered out, leaving the sun rays and the clouds it illuminates red.

Answer 2

It depends on the position of the sun.
As sunlight goes through the air, it bumps into the molecules and dust. When light hits a gas molecule, it may bounce off in a different direction. Some colors of light, like red and orange, pass straight through the air. But most of the blue light bounces off in all directions. In this way, the blue light gets scattered all around the sky.

As the sun begins to set, the light must travel farther through the atmosphere before it gets to you. More of the light is reflected and scattered. As less reaches you directly, the sun appears less bright.
The color of the sun itself appears to change, first to orange and then to red. This is because even more of the short wavelength blues and greens are now scattered. Only the longer wavelengths are left in the direct beam that reaches your eyes.

When you look up, some of this blue light reaches your eyes from all over the sky. Since you see blue light from everywhere overhead, the sky looks blue.
The color of the sky near the horizon appears paler or white because less blue light reaches your eyes.

In space there is no air, so there is nothing for the light to bounce off, it just goes straight. None of the light gets scattered, and the "sky" looks dark and black.

Answer 3

As the time of day changes, the angle that the sun strikes our local atmosphere changes as does the amount of atmosphere that the light must pass through. The varying angle and differing thickness yield different color renditions throughout the day.

Answer 4

The sky changes color based on how much of the atmosphere the sunlight has to pass through.

Answer 5

One is due to refraction of light through the sky to the horizon of the earth and the other is the 'prism' theory - VIBGYOR diversion. Hope, need no explanation.

Answer 6

at different times of the day, the light that reaches the earth from the sun strikes the earth's atmosphere at different angles. this causes the diffraction of that light to change. when the diffraction changes, the color of the light we see changes.

Answer 7

light have different colour.at morning light have to travel distance much longer than at noon.at morning red wavelength reach earth.similarly blue reach earth

Answer 8

cos o SUN...the distance between sun n earth....

Answer 9

depending of clouds and time
