Why Sky Looks Blue Not Violet

Why Sky Looks Blue Not Violet. So it sounds like regardless of what anyone perceives violet to appear as, the explanation for why the sky appears blue and not violet remains the same, correct? It gets scattered all around the sky.

Closer to the horizon, the sky fades to a lighter blue or white. The sunlight reaching us from low in the sky has passed through even more air than the sunlight reaching us from overhead. This is why the sky is blue and the setting sun is red.

Sky Looks Blue Because Because Our Eyes Are Sensitive To Blue Colour.


Now our eye also play a role in making the sky blue. Why is the sky not violet? When white sunlight passes through a lot of atmosphere the blue is scattered out of the beam leaving the red in the beam.

If Shorter Wavelengths Are Scattered Most Strongly, Then There Is A Puzzle As To Why The Sky Does Not Appear Violet, The Colour With The Shortest Visible Wavelength.


Though violet has the shortest wave length, the sky looks blue, not violet. Rayleigh scattering means the shorter wavelengths will be scattered much more than longer wavelengths, which explains why the sky isn't red or green. Whichever direction you look, some of this scattered blue light reaches you.

As The Sunlight Has Passed Through All This Air, The Air Molecules Have Scattered And Re Scattered The Blue Light Many Times In Many Directions.


This is because the sun emits a higher concentration of blue light waves in comparison violet. So it sounds like regardless of what anyone perceives violet to appear as, the explanation for why the sky appears blue and not violet remains the same, correct? It appears a brighter blue the farther away from the sun you look, because there's more atmosphere to see (and therefore more.

This Is Why The Sky Is Blue And The Setting Sun Is Red.


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. It gets scattered all around the sky. Also, our eyes are not as sensitive to violet as they are to blue.

This Is Because The Sun Emits A Higher Concentration Of Blue Light Waves In Comparison Violet.


But the most strongly scattered indigo and violet wavelengths stimulate the red cones slightly as well as the blue, which is why these colours appear blue with an added red tinge. The intensity of the violet produced by the sun is less than blue. At sunset and sunrise, the sunlight passes through more atmosphere than during the.
