Why is there a rainbow hanging in the sky, and what does a rainbow look like in the sky?

Rainbows are caused by the emission and refraction of sunlight into water droplets in the sky.

We know that when sunlight passes through the prism, the direction of the foreground is deflected, and the original white light is removed.

The thread is broken into 7 color bands of red, orange, yellow, green, cyan, blue, and violet.

After rain, there are many tiny water droplets floating in the air, and when the sunlight hits the small droplets, they will be refracted and dispersed.

into 7 colors of light. Many small water droplets refract the sunlight at the same time, and then reflect it into our eyes, and we will see one.

A semicircular rainbow. The color bands of the rainbow are distinct, with the red one coming out on the outside, followed by six types: orange, yellow, green, cyan, blue, and purple.

Color. The size of the water droplets in the air determines the brightness and width of the rainbow. When the water droplets in the air are large, the rainbow is bright. Also.

Narrower; On the contrary, if the water droplets are small, the rainbow color will be lighter and wider.

We can't see the rainbow when we face the sun, we can only see the rainbow with the sun on our backs, so the rainbow appears in the morning.

In the west, the rainbow at dusk always appears in the east. But we can't see it, we can only see it when we look down from a high altitude by plane.

The appearance of the rainbow is related to the change of the weather at that time, and we can generally infer from the position of the rainbow in the sky.

Sunny or rainy. When there is a rainbow in the east, it is not easy to rain locally, while when there is a rainbow in the west, it is possible to rain locally.

But the sex is great. The visibility of a rainbow depends on the size of the small water droplets in the air, the larger the volume of the small water droplets, the brighter the rainbow formed, and the smaller the size of the small water droplets, the less obvious the rainbow formed.

In winter, the temperature is low, small water droplets are not easy to exist in the air, and there are few opportunities for showers, so there are generally no rainbows in winter.

After the rain, there will be a large number of small water droplets suspended in the air, when the light passes through these water droplets, the light will be refracted phenomenon, and because in the refraction process of light, red, orange, yellow, green, blue, indigo, violet and other colors of light have different refractive angles, forming a rainbow.

Rainbow, also known as Tiangong (Hakka), rainbow, Jiang, etc., referred to as rainbow, is an optical phenomenon in meteorology, when the sunlight shines on the water droplets in mid-air, the light is refracted and reflected, forming an arched colorful spectrum on the sky, from the outer circle to the inner circle is red, orange, yellow, green, blue, indigo, purple wearing eight colors. In fact, the rainbow comes in an infinite number of colors, for example, there are many subtle colors between red and orange, but for the sake of simplicity, only seven colors are used as a difference.

1. The rainbow has become a vague memory. 2. The rainbow hangs in the sky like a crooked colorful bridge.

3. The rainbow hangs in the sky like a beautiful necklace.

4. The rainbow hangs in the sky like a child's slide.

5. The rainbow hangs in the sky like a beautiful colorful dress.

6. The rainbow hangs in the sky like a colorful silk scarf.

7. The rainbow hangs in the sky like a wisp of sunset hanging in the sky.

8. The rainbow hangs in the sky like a mysterious river.

9. The rainbow is like a bouquet of flowers, which is woven into the blue skirt and hangs in the sky.

Rainbows are a natural phenomenon that usually appears after rain. It is formed by the refraction, reflection, and refraction of the sun's rays after passing through the raindrops. The color of the rainbow is produced by the refraction and reflection of light rays in raindrops, and different colors of light rays are refracted at different angles in the raindrops, so they disperse into a spectrum of different colors.

The formation of a rainbow needs to meet certain conditions, and Qingmu Ye first needs to have solar rays, then raindrops or water droplets, and finally observers. When the sun's rays pass through the raindrops, they are refracted and reflected and refracted again, forming an arc-shaped spectrum. The colors of the rainbow are usually red, orange, yellow, green, blue, indigo, and violet, and the order in which these colors are arranged is determined by the angle at which the light rays are refracted in the raindrops.

The appearance of a rainbow is usually after the rain because the raindrops can act as a refractive medium for light rays. When the sun's rays pass through the raindrops, they are refracted and reflected and refracted again, forming an arc-shaped spectrum. The position of the rainbow is usually in the space between the sun and the observer, so the observer needs to stand in the direction of the sun and rain to see the rainbow.

Overall, the rainbow is a beautiful natural phenomenon, and its appearance requires certain conditions to be met, including the sun's rays, raindrops, and observers. The color of color is produced by the refraction and reflection of light in raindrops, and different colors of light are refracted at different angles in raindrops, so they are dispersed into different color spectrums. The appearance of the rainbow, usually after the rain, is a natural spectacle.

Just after a rainstorm, I opened the window and watched the white clouds drift by. Suddenly, a colorful rainbow appeared in front of him. Let's take a look at why there is a rainbow in the sky, just for your reference!

Rainbow is an optical phenomenon in meteorology, when the sun's rays hit the water droplets in the air, the light is refracted and reflected, and it will form an arched seven-colored spectrum on the sky, that is, a rainbow.

In the summer, when the sun regains its smiling face after the rains, we often find a semicircular rainbow in the sky opposite the sun. So, why do rainbows appear in the sky?

It turns out that the beautiful rainbow is caused by the dispersion and reflection of the sunlight into the air with small water droplets that are almost spherical in shape. When sunlight hits a water droplet, it is incident at different angles at the same time, and it is reflected at different angles within the water droplet. The reflection of 40 to 42 degrees is the most intense, resulting in the rainbow we see.

This reflection is caused when sunlight enters the water droplets, first refracted once, and then in the water droplets. The back reflection is followed by a second refraction when it finally leaves the droplet, for a total of two refractions after one reflection. Because water has a dispersive effect on light, the refractive index of light of different wavelengths is different, red light has a smaller refractive index than blue light, and blue light has a greater deflection angle than red light.

Because the light is reflected inside the water droplet, the observer sees the spectrum upside down, with red light at the top and other colors at the bottom. As a result, rainbows and neon are not the same heights, and the order of color cascades is reversed. A rainbow means that light is refracted twice and reflected once, while neon is light that is refracted twice and reflected twice.
