Introduction to rainbow
Rainbow, in fact, as long as there are water droplets in the air and the sun shines behind the observer at a low angle, it is possible to produce an observable rainbow phenomenon. Rainbow usually appears in the afternoon, when it just cleared up after the rain, and the air was less dusty and full of water droplets. One side of the sky is dark, because there are still rain clouds, and the sun can be seen above or behind the observer without cloud cover, so the rainbow will be easier to see.
Another place where rainbows are often seen is near waterfalls. When the weather is clear, you can spray water or mist into the air with your back to the sun, or you can create an artificial rainbow. Moon rainbow, also known as night rainbow, is a very rare phenomenon, which may appear in the night with strong moonlight. Because it is difficult for human vision to distinguish colors in low light at night, the night rainbow looks as if it is all white.
