The Truth About Why The Sky Is Blue, As Told By Teen Titans Go!

 

• In the episode, "Permanent Record" of Teen Titans Go!, when Robin makes all the Teen Titans have a day of class as if they're in school, they take a trip into outer space to learn about astronomy. Starfire asks why the sky is blue and Robin tries to explain to them that the sky is blue because of the sunlight reflecting the blue color of the oceans, but Beast Boy corrects him and explains the real reason why the sky is blue is because the sun blows out a multi-colored light, of which the innermost color is blue; and the gaseous particles in the Earth's atmosphere tend to reflect the blue part of the sun's light more than any of the other colors. Robin gets angry at Beast Boy for interrupting him and even thinks that he is wrong for the answer he gave, but it turns out Beast Boy is actually correct. In addition to that, this is actually a real-life scientific fact: The sky is blue (and to a certain extent, the oceans too for that matter) because of the concept of Raleigh Scattering, which means that when the sun's light reaches the Earth, the smallest wavelengths of light tend to scatter easier, and because blue and purple (and to a lesser extent, red and orange such as at dusk and dawn) have the smaller wavelengths of the other colors of the sun's light, and because of electromagnetic radiation coming from the sun's light, the Earth's atmosphere and the oceans reflect this blue light better than any other color from the sun's light and it is easier for us human beings to see these blue wavelengths on the visible light spectrum, better than any of the other colors.
