When it rains, the colors that make up white light separate because they bend at different angles when they pass through water. The result is the full spectrum of colors the human eye can see, as well as some that it cannot; at the outermost edges of a rainbow lie ultraviolet and infrared light.
下雨时，那些构成白色光的颜色穿过水滴时以不同的角度被折射而散开，就形成了完整的光谱，其中有些颜色肉眼能看得到，有些看不到；彩虹的最外围是紫外线和红外线。
