神奇的双彩虹

JOJO：“我刚才操作展项时，发现了两道彩虹……”

彩虹：“嗯，你观察得真仔细！是不是发现外侧的彩虹颜色较暗，而且两道彩虹的颜色顺序是相反的？”

JOJO： I actually saw two rainbows when I operated the exhibit.

Rainbow： Yes，you observed very carefully. Did you find that the rainbow on the outside is darker，and the color sequences of the two rainbows are opposite？

JOJO：“是的，这看上去好神奇呀！”

彩虹：“人们经常看到的是主虹，外侧较暗的叫作霓或副虹。”

JOJO：“哦，从外表看上去霓比虹要暗一些。”

JOJO： Yes！ This is amazing！

Rainbow： People usually can see the primary rainbow. The fainted rainbow on the outside is called neon or secondary rainbow.

JOJO： Oh，yes. Neon looks darker than the primary rainbow.
