colour

People generally know the sky is blue, yet few understand its fascinating science behind this optical effect. Color results from waves passing through an object being reflected, refracted or scattered back onto itself with some frequencies being absorbed while others pass right through. Lord Rayleigh first noted that atmospheric particles scatter blue light more strongly…

When we gaze upon the sky, its color usually appears blue. This hue comes from light being scattered by molecules in our atmosphere. Blue wavelengths tend to get scattered more, making them appear brighter than their longer-wavelength counterparts. Other colors may also appear differently depending on factors carried through the air such as weather or…
