The same reason there are rainbows in the sky: the rain acts as a prism, which splits the sunlight into it's different colors.

∙ 7y agoIt's not a 100% for a rainbow to appear after a rain. Sometimes, a rainbow does'nt appear especially at night but during night there is a rare rainbow called a "moonbow" but it can only be seen during full moon. When there is a flash flood, the water droplets aren't stable enough to create a rainbow. Sometimes just after rain, it remains cloudy.

Can you touch a rainbow?
Because its an optical illusion. It looks like it falls on the horizion, but the more you travel towards it, it remains the same distance away. The rainbow that you actually see is only part of a circle of the rainbow in the sky. We normally only see a segment or an arc from horizion to horizion. On certain conditions when the upper level atmosphere is just right, an entire circle of the rainbow can be seen and on rare occasions, even multiple ones. == ==
