why is the sky blue and why does it turn orange-red at dusk?

Question

reasons for the colour of the sky

Answer 1

the reason is jus as simple as follows...

during dusk the rays from the sun have to travel a longer distance and hence redlight which ha the longest wavelength alone reaches the earth..(the other rays get scattered).

during day ....
the blue light gets scattered and they reach ur eyes...
as the distance is short....
u can use the rayleigh's scattering law to explain it

Answer 2

the sky is blue due to the reflection of the water and the molecules,....it turns orange- red at dusk because the Earth rotates therefore it is farther away from the Sun...it is actually the beauty of the Sun thats orange-red

Answer 3

The answer is prisms. The sun releases White light. when it hits the atmoshpher the white light splits into the defferent sphers of light red being the slowest and blue being the fastest. Because blue is the fastest it escapes the atmospher so you get blue skies. Now when get red downs and sun sets it is because of particles in the air(Like smog in California) Red light bounces off the particles causing a red glow. What is really happanning is the light is slowing down when it goes through these particles so it turns to red light. and so that is what you see.

hope this helps

It's blue coz in the morning the blue color compensates and irt has the shorter radiation so isky appears blue
and in the evening the red with the longer radiation dominates in the absence of light so sky appears red at the dusk.

Sorry i'm in chat so can't make a clear answer.
But the above mentioned is right.

Answer 5

as the original color of sky is black according to scientistbut when the light of sun get dispers with the moisture in the air,and so the spectrum, formed but from all 7 colors only blue color get dispersed through all over the sky due to its wavelength,so the sky appears to be blue in color. and some time it appears to be re in color as the red color from the spectru mget dispersed and red color got more wave length so it appears to be reddishyello or orange in color when the sun is setting or rising.

Answer 6

the sky is blue because the light reflected off the atmospher shows blue the red is from the pollutants in the air

Answer 7

sky is actually completely black, but air has a tendency to change colour ie, due to our atmosphere sky appears blue whereas it looks completely black in space.
