Blue - Why Is The Sky

has the longest wavelengths and travels in long, lazy waves.

As sunlight enters Earth's atmosphere, it strikes molecules of nitrogen and oxygen—the gases that make up most of our air. These tiny molecules are much smaller than the wavelengths of visible light, causing them to scatter the light in all directions. Why Is the Sky Blue? | NASA Space Place why is the sky blue

have the shortest wavelengths and travel in short, "choppy" waves. 2. Rayleigh Scattering has the longest wavelengths and travels in long, lazy waves

The sky appears blue primarily because of a phenomenon called , which occurs when sunlight interacts with the Earth's atmosphere . Although sunlight looks white, it is actually made up of all the colors of the rainbow, each traveling at a different wavelength. 1. The Science of Sunlight and Wavelengths Rayleigh Scattering The sky appears blue primarily because

Sunlight is a spectrum of visible light that includes red, orange, yellow, green, blue, indigo, and violet.
