septum jewelry wholesale How does the rainbow form a rainbow picture

jewelry wholesalers in china Rainbow is an optical phenomenon in the weather. When the sun shines into the rainy point in the air, the light is refracted and reflected, and the arched colorful spectrum is formed on the sky. The colorful color of the rainbow is red, orange, yellow, green, blue, 靛, and purple. So how does rainbow form? The following is the principle of rainbow formed by me. Welcome to read.

The rainbow forms a rainbow because the sun shot into the water droplet of the air, and the reflection and refractiveness of the light occur
. , Caused and reflected. When the sun is shot into the water droplet, it will be incorporated at different angles at the same time, and it is also reflected from an unused angle in the water droplet. Among them, 40 to 42 degrees reflection is the strongest, forming the rainbow we see. When this reflection is formed, the sun enters the water droplet, reflects it once, then reflects on the back of the water droplet, and finally reflects once when the water droplets are left.
The place where the rainbow is often seen is near the waterfall. It is easy to see in the clear weather. In the sunny weather, the sun can sprinkle water or spray water mist in the air, and it can also make rainbow artificially.
The colorful color and width of the rainbow are affected by water droplets in the air. The water droplets in the air are large, and the rainbow is bright and narrow; on the contrary, the droplets are small, the rainbow is light and wider. We can't see the rainbow in the face of the sun, and we can see the rainbow only carrying the sun. Therefore, the rainbow in the morning appears in the West, and the rainbow at dusk always appears in the east, but we can't see it. Only the plane is looking down from high altitude. The appearance of rainbow was linked to the weather at that time. Generally, we can speculate that there will be sunny days or rainy days at the time when the rainbow appears in the sky. When the rainbow is in the east, the possibility of rain in the local area is less likely to rain.
So why do the rainbow often appear after the rain in summer? Because it is often rainy in summer, the range of rain is not large, often the sky here is raining, and the sky over there is still the sun. At this time, the rain is raining. There are still many small water droplets floating in the later sky. When the sunlight passes through these small droplets, the refractive effect has a beautiful rainbow in the sky.
The principle of rainbow formed Rainbow is a kind of atmospheric phenomenon. When the air is rich in a large amount of water vapor, it is irradiated by the sunlight at a smaller angle. ribbon.
The rainbow is actually divided into two types. One of the short -rangers radius is red, and the outside of the long radius is purple. "The inner side with a shorter radius is purple, and the long radius is red. Rainbow and Ni sometimes coexist, sometimes there is only rainbow but no neon. The rainbow phenomenon formed by the sun and the rainbow is a rainbow phenomenon reflected by small water beads and reflection. The light is reflected by the water drops twice and once is called the rainbow; the light is reflected by the water droplet twice and twice is called the neon. Because neon reflexes are more frequent, the strength of the light is weak, so it is not common.
It because the neon and the rainbow reflection path is different, we see that the seven colors of the neon just happen to be the opposite of the seven colors of the rainbow. The rainbow appeared in the morning and evening. At this time, the sun was closer to the horizon, and the angle of illumination was very low. If in the morning, the sun rises from the east, then the rainbow will appear in the west of the sky; if it is in the evening, the sun sinks, and the rainbow will appear in the east sky. Most of the rainbow appear after the rain, because after the rain, there are a lot of water vapor in the air. At this time, the sun comes out and the water vapor is more prone to rainbow. However, there are special circumstances that the climate is humid. In fact, it may be because it is raining in the high altitude, but the water vapor does not reach enough. It has evaporated before the rain until the ground is too late.
, there are still many small droplets in relatively high air. At this time, the sun came out of the water droplets in the air, and a beautiful rainbow appeared. Rainbow is formed by the rain drops in the air like a triangular poison, so the rainbow usually appears when there is a sun during the day. However, it is amazing that there will also be rainbow at night, but it is not the daybow of the day, but Yuehong.
, like the daybow of the day, the formation of Yuehong also requires light sources. Although there is no sun at night, if there is a bright moonlight and a proper cloud droplet in the atmosphere, the moonburies can be formed. The moon reflects the sunlight, so the moonlight is also composed of the seven visible monochrome lights of red orange, yellow, green, blue, blue purple, and reflect the moonbird. However, the moonlight is much weaker than the sun after all, so the Yuehong formed is not as bright as the sunbow, and can only be seen when it is approaching the full moon.
The photographer Chris Walker, who captured the beautiful scenery of Yuehong, said: "I found that the scene in the sky was different from usual when I was driving home. I was a full moon behind me. The clouds fell in the clouds. When I got home, the moon was very bright, so I clearly saw that the scene in the sky was actually a rainbow formed by the moonlight. "
Different, the inverted rainbow is called the phenomenon of magic sun in astronomy, and it looks like an inverted rainbow.
The rainbow that people often see are a seven -color spectrum generated by raindrops or fog drops to the sunlight. The formation of the fantasy sun arc is clear and very small in the sky, and the clouds are very small. At the same time, the sunlight can also illuminate a small ice crystal from the cloud layer 6100 meters -7625 meters from the ground. In addition, the surface of the ice crystal in the clouds must be bent, and the particles are smaller than salt particles.
In fact, except for the different conditions and the rainbow, the spectral order of the fantasy sun arc light is different from the rainbow. The color arrangement of the fantasy day arc is purple at the top, the red is at the bottom, just the opposite of the rainbow. And because the ice crystals in the rolling cloud will continue to change the direction, the time of the fantasy sun arc is extremely short.
