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
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
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 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?
Is there more to the the conventional explanation of Why is the sky . . . An important note: If the Rayleigh formula were accurate (which it is), then the color of visible light most scattered wouldn't be blue, but rather violet, which is of a shorter wavelength We should by all means seeing a purplish sky instead, but it just so happens that our [eyes are more sensitive to blue light than violet] [1] so the blue color predominates in our vision [1
The blue sky — is the simple Rayleigh explanation wrong? Can you explain why you (or your sources) claim water scatters "way less" light than air? When we look at the blue sky we're looking through something like 50km of air About 200m down in the water it's essentially pitch black
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 wavelength of violet colour less than wavelength of blue colour? Now, when it comes to violet, its wavelength is the least in the visible spectrum It is made by the mixture of red and blue So according to my logic, it should lie between red and blue in the spectrum But it doesn't, its wavelength is less than wavelength of blue How is this possible?
