- Why is the sky not purple? - Physics Stack Exchange
The net effect is that the red and green cones are stimulated about equally by the light from the sky, while the blue is stimulated more strongly This combination accounts for the pale sky blue colour It may not be a coincidence that our vision is adjusted to see the sky as a pure hue
- visible light - Why is the sky never green? It can be blue or orange . . .
Can you explain why the colour of the sky passes from blue to orange red skipping altogether the whole range of green frequencies? I have only heard of the legendary 'green, emerald line flash' that appears in particular circumstances Green flashes are enhanced by mirage, which increase refraction is more likely to be seen in stable, clear
- optics - Why does the sky change color? Why is the sky blue during the . . .
Blue light is scattered more than red light, so during the day when we look at parts of the sky that are away from the sun, we see more blue than red During sunset or sunrise, most of the light from the sun comes towards the earth at a sharp angle, so now the blue light is mostly scattered away, and we see mostly red light
- Why is the sky *uniformly* blue? - Physics Stack Exchange
It's not clear why the color should not rapidly change from near blue at horizon to almost red near the Sun position: after all, the atmosphere is thicker along the lines going closer to horizon! The sky seems to be more uniformly blue than the typical explanation suggests
- Why is the sky blue and the sun yellow? - Physics Stack Exchange
The blue color of light of the sky is due to Rayleigh scattering But the sun itself appears yellow in color whereas the scattered sunlight itself appears blue Why does this happen? Should the sun
- Why is the sky blue: For a 3-year old - Physics Stack Exchange
Why does the sky change color? Why is the sky blue during the day, red during sunrise set and black during the night? (5 answers) Closed 10 years ago My nephew asked me yesterday why the sky was blue I tried to explain it to him as best and as dumbly I could, but I failed
- Why is the sky red only in the west but not in the east during sunset . . .
2 So I understand the basic principles of the scattering of light and how the shorter wavelengths like blue and green are scattered more during sunset sunrise, causing us to see mainly the red light If this is the case, how come if you look at the opposite side of the sunset to the east, the sky still appears blue?
- Why is there a blue hour after the golden hour?
17 There's a great story about why the sky is blue during the day, and turns golden during sunsets: Rayleigh scattering affects blue light more During the day, blue light from the Sun is scattered towards us from all directions, causing a blue sky
