Why does sun appear to be red in the morning and evening?

Question

is it becuz sun emits light of higher wavelength??

Answer 1

Close. The other wavelenghts are refracted away by the thickening atmosphere as the sun approaches the horizon.

Answer 2

This is due to scattering of shorter wavelength (blue) light by particles in the earth's atmosphere.

When we look at the sky, it appears blue because we see the scattered light (blue). When the sun is setting (or rising) it has more atmosphere to pass through because it is path is at a shallower angle to the earth's surface. We see the TRANSMITTED light which is "missing" a large proportion of the blue light, hence it looks red.

You can simulate this in the home by putting a couple of drops of milk in a container of water. If you shine a light through it, it will have a yellowish / orange tinge. The scattered light will be light blue.

Answer 3

Its because the light goes through more atmosphere in the morning and evening due to the angle, so the light gets slowed down to a red wave length

Answer 4

Light generated by the sun at dawn and sunset is the same all the time. At dawn and sunset that sunlight must pass through about 65% more of Earth's atmosphere than when the sun is higher in the sky. Earth's atmosphere contains lots of dust and pollutants (..smog..) that discolors the sunlight.

Answer 5

No, the light being emitted by the sun stays the same.

As the sun moves overhead, you see it through atmospheric layers of differing thickness. This is what causes the colour to change.

Answer 6

no. because the sun's light travels through more atmosphere before it reaches your eyes.

Answer 7

No, it is because the light has to travel through more atmosphere to get to you do it changes color.

Answer 8

all the answers are good
