雨后新霁时,空中残留着许多小水滴.在阳光的照耀下,有时会在太阳对面的天空中出现瑰丽多彩的长虹——虹霓.虹霓是阳光射入小水滴后经折射、反射,形成在雨幕或雾幕中的彩色圆弧.这种圆弧常出现两个:红色在外,紫色在内,颜色鲜艳的叫“虹”;红色在内,紫色在外,颜色较淡的叫“霓”. After the rain, there were many small water droplets in the sky. In the sun’s rays, sometimes there will be colorful and colorful rainbows in the sky opposite the sun - Hauni. Hauni is the reflection and reflection of sunlight when it hits small water droplets. A colored arc formed in a curtain of rain or a curtain of fog. There are often two such arcs: red is outside, purple is called, and brightly called “Rainbow”; red, purple is out, and lighter is called “ Ne.”
