I can't help sighing how wonderful nature is! I wonder how this rainbow was formed. So I looked up some information on the internet and learned that rainbow is a colorful arc in the sky after rain, a light phenomenon in the atmosphere and formed by the refraction and reflection of sunlight on water droplets in the sky. The rainbow consists of seven beautiful colors, namely, red, orange, yellow, green, cyan, blue and purple. But most colors are reddish and green.
Just when I was ecstatic to find the answer, I suddenly found that the rainbow outside the window was about to disappear. I quickly grabbed the camera and rushed out. Just as I was about to take some photos as a souvenir, the rainbow just didn't wait for the children who loved it. After a while, the rainbow slowly disappeared without a trace. ...
Rainbow is really a wonderful gift from nature! As long as we have a pair of smart eyes, we will discover more natural mysteries. ...
