Summertime! Yay! Our last day of school was yesterday, I'm so happy! Woohoo summer!
And just now, I looked out the window and there was this absolutely gorgeous double rainbow, half in the sun, half not, right as the sun was going down. So pretty! And what's funny is one rainbow goes left to right, purple to red, and the other one goes red to purple. Apparently this happens because the light coming from the sun is reflected twice inside the raindrops. The light emerges from the raindrop at a different angle than it does the first time. In the first rainbow the blue light emerges from the drops at a smaller angle than the red light, but in the second, the blue light emerges at a larger angle than the red light. Therefore it seems "flipped" to us. Whoa. Science. Cool stuff.
Congratulations. You learned something today:)
