你看到的是一个主虹(彩虹# 2在链接的图像),它的二次彩虹(# 4),一个(反射彩虹)(https://www.atoptics.co.uk/rainbows/reflect.htm)(# 1),及其二级(# 3)。注意:相关文章称这些反映了彩虹,但这是不正确的。(反映彩虹)(https://www.atoptics.co.uk/rainbows/rflctd.htm)是另一种大气光学现象,发生在一个似乎看到彩虹的反射,水在观众面前。背后的水是摄影师的链接图片,和额外的两个彩虹在天空中而不是在水里。(没有水的形象有关。)水的反射阳光的背后观众导致反射彩虹在观众面前。彩虹的中心主要是对日点彩虹的从观众的角度来看,这是低于地面。彩虹是一种反映的中心的anthelic点反射的太阳,这是离地面。因此彩虹# 1,主虹从太阳本身,低于彩虹# 2,主彩虹背后的尼斯反射来自太阳的摄影师。这两个彩虹相交于地面。 Rainbows can have secondaries, and so can reflection rainbows. These are bows number 4 and 3. Note that the sky and land are darker between the primary and secondary, brighter outside the secondary, and much brighter inside the primary. The lighting outside the secondary is the natural lighting level. One way of looking at rainbows is that they transfer some of the light that would normally fall between the primary and secondary to inside the primary, and that this transference changes a bit with frequency.
