Because sunlight itself has different colors, it will form seven ribbons when it shines on water droplets.

If the water drops are bigger, the color of the rainbow will be brighter and more beautiful. Under normal circumstances, you can't see the rainbow with your back to the sun. You can only see the rainbow with your back to the sun.
Many people think that the rainbow is curved. In fact, this is because when normal people look at the rainbow, they will find that the rainbow is semi-arc in the air. However, if we look at the rainbow from a higher place, we will find that the rainbow is round, and the rainbow we see is incomplete, just because our position blocks the rainbow, which is the real shape. At the same time, it should be noted that the position of the rainbow is not fixed, but will change, so it is difficult to see what the side of the rainbow looks like.
