Rainbow encountered lightning

What wonderful combination is this

Rainbow is actually more than 7 colors

There was a thunder shower yesterday evening, but why did not have a rainbow in Hangzhou yesterday?

Because the formation of the rainbow, in addition to sufficient water droplets in the air, also requires sufficient sunlight and harsh angle. Scientific research shows that the best angle of the formation of rainbow water drop reflection is 40-42 degrees. Only from this angle range can achieve sunlight shot into the water droplets not only reflected once, but also reflected once on the back of the water droplet, so that the color of the rainbow color will It appears more clearly.

People often say that there are seven colors of rainbow, but in fact, the genealogy of the sun is continuity. There is no clear boundary between the color of the rainbow. You say it can have millions of colors, and everyone's sensitivity to the color is also the color. different. The Chinese generally believe that the rainbow is composed of red, orange, yellow, green, green, blue, and purple, but Westerners believe that it is composed of red, orange, yellow, green, blue, 靛, and purple.

And another Greek philosopher color Nuoffini said that the rainbow is three colors: red, yellow -green and purple. In the Renaissance (13-16 century), people believe that there are four colors of rainbow: red, yellow, green and blue. After that, people added the fifth color, purple.

The first seven -color rainbow was first proposed by Newton in 1666. At that time, Newton did not observe the seven colors, but he believed that everything in the universe existed in the seven stars (at the time that he had not found Uranus and Pluto). There were seven days a week and seven notes. Colorful, so in the five -color rainbow that people was recognized at the time, orange was added, and purple was divided into 靛 and purple.

Rainbow is actually full round

In Chinese mythology, the rainbow is a dragon or snake with a double head, which can go down the river to drink water. In Western folklore, the elves will collect the treasure at the end of the rainbow. In fact, the rainbow is not ending because it is round!

The rainbow that people usually see is just a bridge -shaped half -curved. That's because we stand on the ground and can only see the water droplets above us. Therefore, we can only see the upper part of the rainbow, and the lower part of its part is The horizon blocked. But if height is sufficient, the full circular rainbow may be observed.

On July 2 this year, double rainbow appeared in Shizhen County, Guizhou Province. In the case of high enough, some people took the rare rainbow circle.

Besides, a cold knowledge, Rainbow belongs to privately customized products. The rainbow in different people's eyes is different. Even the same person, the left and right eyes are different, because the rainbow center that everyone sees is located in the sun and themselves. On the connection.
