Every sunset ends with a green flash. Why is it so hard to see?
The climax of every sunset is green. But it hard to see you can try to catch it, if you can. The question of green flash of sunset is begins by answering the question that: Why is the sky blue?
The rays of sun have every visible color and each has its own wavelength. The sun light travel as ripples with valleys and crests. The ripples the steeper depends on the length of wavelength.
From the three primary colors RGB (Red, Green and Blue), blue has the shortest wavelength and the red has the longest wavelength.
When the light of sun hits Earth then than due to Blue light steeps wave’s particle scatter totally into air and turning our skies cerulean. The leftovers mixed up to create the sun’s yellow glow.
During sunset the sunlight color fade at varying rate. Just before the sunset the red light shallower ripples cause it to shoot overhead and miss your eyes.
Green, with its steeper wavelength remains the sole color survivor, just for a second.
Every evening the green flash may happen but it’s hard to catch it due to atmospheric conditions like pollutions and fog, can wrap and deflect the green flash before it reaches our eyes.
