A rainbow is an optical phenomenon in meteorology. When sunlight hits raindrops in mid-air, the rays are refracted and reflected, forming an arched spectrum of colors across the sky. The rainbow of colorful colors, from the outside to the inside, are:
Red, orange, yellow, green, blue, indigo, purple.
Rainbow is a natural phenomenon caused by the reflection and refraction of light from sunlight into water droplets in the air.
-
It should be red, orange, yellow, green, blue, purple, but sometimes the rainbow changes!
-
Red, orange, yellow, green, blue, indigo, children's books should be easy to understand.
Therefore, it is more concise, and the color of light should be red, orange, yellow, green, blue, indigo, and violet.
-
The colorful colors of the rainbow, note from the outside to the inside: red, orange, yellow, green, cyan, blue, and purple.
-
Purple, blue, cyan, green, yellow, orange, red, and other seven colors are sorted.
-
The order of the seven colors of the rainbow is: red, orange, yellow, green, cyan, blue, and violet.
Rainbow is an atmospheric optical phenomenon that usually appears just after rain when the sky is clear, and it is the sun's rays that hit water droplets in mid-air, causing dispersion and reflection. The light rays are refracted at different angles and then reflected at different angles within the water droplets, creating a rainbow with a curved shape, usually semicircular, and brightly colored. The rainbow is from the outer circle to the inside, and the colors are red, orange, yellow, green, blue, indigo, and purple.
Regarding the color of the rainbow, it is also said that it is red, orange, yellow, green, blue, and purple, but the rainbow also has more than seven colors, for example, there are many subtle differences between red and orange, but for the sake of simplicity, seven colors are used to distinguish them.
Why rainbows always come after rain
Generally, there is no rainbow in the process of rain, because it is cloudy at this time, and the sun is blocked by the clouds in the sky, and there is no rainbow without sunlight. And when the rain just ended, the sun came out, but the clouds were still raining not far from us. So there will be a lot of small droplets in the air not far away.
Sunlight penetrates these droplets, and there is one reflection and two refractions in the droplets.
It was the sunlight that hit the water droplets and turned three corners. The sunlight is originally white, but after three turns in the stomach of the water droplet, it is scattered and becomes seven colors of light into our eyes, and we see a rainbow.

From the outside to the inside, they are: red, orange, yellow, green, blue, purple; This arrangement is determined by the wavelengths of the individual colors, and actual observations of rainbows and explanations in physics books indicate that red with a small refractive index should be on the outside, and purple with a large refractive index should be on the inside. For the pararainbow formed by reflection twice, the color order is outer ultraviolet and inner red.
However, the brightness of the secondary rainbow is much darker than the main rainbow and is not easy to observe, and the secondary rainbow is located above the main rainbow, and there should be a main rainbow below the secondary rainbow.
-
This is due to the color of light.
In fact, our world is so wonderful because of the dispersion of light!
In fact, what we usually call light is actually a polychromatic light, which is composed of red, orange, yellow, green, blue, indigo, and violet, these seven colors of monochromatic light!
And the rainbow is not just these seven colors, but the main colors of red, orange, yellow, green, blue, indigo, and the excessive colors between them

From the outer ring to the inner ring, there are seven colors: red, orange, yellow, green, blue, indigo, and purple.
The rainbow is actually the dispersion of light, that is, the refraction of light. As long as there are water droplets in the air and sunlight is shining at a low angle behind the observer, a rainbow phenomenon that can be observed can be produced. Rainbows are most common in the afternoon, when the weather clears after the rain.
At this time, the air is less dusty and full of small water droplets, and one side of the sky is darker because there are still rain clouds. The rainbow will be easier to see if the sun is visible without clouds above or behind the observer's head. Another place where rainbows are often seen is near waterfalls.
Splashing water or spraying water mist in the air with your back to the sun on a sunny day can also artificially create a rainbow.
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.

The colors of the rainbow from the outside to the inside are red, orange, yellow, green, blue, indigo. Rainbow is an optical phenomenon in meteorology, when the sunlight hits the water droplets in the air, the light is refracted and reflected, and it is easy to form an arched colorful spectrum in the sky, which is common after rain. The colors of the rainbow from the outside to the inside are red, orange, yellow, green, blue, indigo.

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
