Anonymous users2024-02-07Rainbow is a natural phenomenon caused by the reflection and refraction of light from sunlight into water droplets in the air.
We know that when sunlight passes through the prism, the direction of travel is deflected, and the original white light is broken down into bands of red, orange, yellow, green, blue, indigo, and violet. When it rains, or after rain, the air is filled with countless tiny droplets that can deflect the sun. When sunlight passes through water droplets, it not only changes the direction of travel, but is also decomposed into red, orange, yellow, green, blue, indigo, violet and other colors.
If the angle is right, it becomes the rainbow we see. Generally speaking, rainbows only occur in summer, because there are many showers in summer, and sometimes, the sun rises in the east and it rains in the west, and the rain is not large. Winters are cold and dry, with little rain, and snowfall does not form rainbows.

Anonymous users2024-02-05A lot of water droplets in the air.
And then the light comes through the droplets, and it refracts into your eyes, and it's a lot of colors, and that's the rainbow.
Refraction can split white light into a lot of light This is dictated by the laws of nature There is no reason so don't ask.

Anonymous users2024-02-03Rainbows are caused by the dispersion and reflection of light caused by the direct sunlight hitting small water droplets in the sky that are almost round.
Rainbows usually appear after rain or in the afternoon, and their shape is curved and arched, showing seven brilliant colors in the sun, which is a very beautiful sight. The smaller the wavelength, the greater the refractive index, so the refractive index of violet light is large and the refractive index of red light is small.
Regarding the color of the rainbow, the most common saying in China and Southeast Asia is: red, orange, yellow, green, cyan, blue, and violet, which are the seven primary colors decomposed by the famous scientist Newton.
Rainbow Meaning: The rainbow symbolizes beauty, fairy tales, and good luck. Rainbows only appear after rain, indicating that the beauty to be pursued will only be achieved after experiencing certain setbacks.
In addition, different civilizations have different beliefs about rainbows. According to Greek mythology, the rainbow was a bridge between heaven and earth. And the ancient people of Serbia, believed that the rainbow was the bow of the storm god.
The rainbow is a universal symbol of peace and harmony, and on March 14, 1994, the world's longest rainbow appeared over Sheffield, England. The rainbow has a beautiful symbol, it means love, lovers can truly understand the color spectrum of love after tasting the ups and downs of love. The rainbow symbolizes beauty, fairy tales, nature, fantasy.
Rainbow, also known as Tiangong (Hakka), rainbow, Jiang, etc., referred to as rainbow, is an optical phenomenon in meteorology, when the sun's rays shine 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 seven 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. <>

Anonymous users2024-02-02Rainbows are caused by the dispersion and reflection of small water droplets in the sky that are almost spherical in the sky. 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.
How rainbows are formed.
Hello dear, I'm glad to answer for you [Open Posture Imitation Heart], the rainbow is caused by the fact that the sun hits the air and is close to the spherical small water droplets, causing dispersion and reflection. When the sunlight is vertically hit into a water droplet, it will be incident at different angles at the same time, and the water droplet will also be reflected at different angles.
The basic conditions for the formation of rainbows are water vapor and sunlight. After the rain, the humidity of the air is high, and the water vapor in the air can be seen as countless small droplets of water in the world. The small droplet is basically spherical in the air, and no matter how it rolls over and over, its shape remains the same in space.
When sunlight hits a small water droplet, two refractions and one reflection occur, the phenomenon of "refraction-reflection-refraction". Different parts of the sunlight hitting the small water droplets will produce different refraction signals and reflection paths. <>

Anonymous users2024-02-011. A rainbow is formed when light passes through water droplets suspended in the atmosphere. Light waves change direction as they pass through water droplets, creating two processes: reflection and refraction.
When light is reflected onto a water droplet, it is reflected back in the opposite direction from where the drop originated. When light is refracted, it goes in a different direction.
2. Rainbows are formed because white light enters the water droplets and bends in several different directions in the water droplets. When these curved light waves reach the other side of the water droplet, they reflect back into the droplet instead of passing through the water completely. Since white light is separate in water, refracted light appears to the human eye to be different colors.
The main wavelength range of visible light is about 390-700nm, and the naked eye has a distinction of about 40nm for the significant difference between the two colors, and the characteristic wavelength of the seven colors is as follows: red 650nm orange 610nm yellow 570nm green 530nm cyan blue 490nm blue indigo 450nm violet 410nm People often ask why there are "red, orange, yellow, green, blue, blue, violet" and "red, orange, yellow, green, blue, indigo", which is more accurate, in fact, both have their own truth, The above theory can give a better explanation. Newton's theory is "red-orange-yellow-green-blue-indigo", which is more biased towards 490nm, while the blue in "red-orange-yellow-green-blue-violet" is more biased towards 450nm. >>>More

The formation of the primitive earth.
Before the formation of the earth, there were many asteroids in the universe revolving around the sun, and these planets collided with each other to form the primitive earth, when the earth was still a hot fireball, and as the collision gradually decreased, the earth began to cool slowly from the outside to the inside, producing a thin layer of hard shell - the earth's crust, at this time the earth was still in a hot state. A large amount of gas is ejected from the inside of the earth, which carries a large amount of water vapor, which forms a circle of atmosphere surrounded by the periphery of the earth, the position of the earth from the sun is not too close to the water vapor is evaporated by the sun, and the size of the earth itself has enough gravity to pull the atmosphere, so the earth will have a unique atmospheric environment, and the atmosphere begins to rain after the formation, and the original ocean is formed. >>>More
The appearance of the bilateral lower limbs of a normal person should be basically straight, and when the inside of the ankle joints on both sides is brought together, the bilateral knees should also be able to come together. When the distance between the two knees is more than 2 cm, it can be called "O-shaped leg" or "knee varus", and it is commonly known as "lap leg". "O-shaped legs" are common in children aged 2 to 6 years and are characterized by the lower limbs not being straight or bent, the distance between the knees is large when the heels are together, making the lower legs feel too bent, and the feet are inwardly figure-eight when walking. >>>More
