The sky is blue because sunlight reaching Earth’s atmosphere gets scattered. As it travels through the air, tiny oxygen and nitrogen molecules scatter light at shorter wavelengths such as blue and violet more so than red and orange wavelengths. When blue light hits gas molecules, it rebounds off them at right angles and your eyes […]

Children often ask why the sky is blue, making it one of the most challenging questions to answer without sounding too technical or scientific. Answer lies within how light travels through our atmosphere. When sunlight enters Earth’s atmosphere, its beams get scattered by gas molecules; longer wavelengths, such as red and orange hues pass more

When sunlight reaches Earth’s atmosphere, it bounces off of molecules. The air molecules scatter light — just like billiard balls do when they collide. The shorter the wavelength of the light, the more it gets scattered. This is why the sun’s light looks blue. Sky Blue Is Due to Rayleigh Scattering Sky blue is a
