What colors are the rainbows! What color is the rainbow

7 species, red, orange, yellow, green, blue, purple.

7 in ah,"""Red, orange, yellow, green, blue, purple.

The colors of the rainbow from the outer circle to the inner circle are red, orange, yellow, green, blue, indigo, and purple.

Rainbow, also known as celestial bow, rainbow, silk, etc., referred to as rainbow, is an optical phenomenon in meteorology. When the sunlight hits the water droplets in mid-air, the light is refracted and reflected, forming an arched multicolored spectrum in the sky, which is red, orange, yellow, green, blue, indigo, and purple from the outer circle to the inner circle.

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. Rainbows most often appear in the afternoon or just after rain when the sky is clear, and their position shifts as the observer's position changes.

The reason for the formation of rainbows

Rainbows are caused by the dispersion and reflection of small water droplets in the sky that are almost spherical in the sky. When sunlight hits the water droplets, it will be incident at different angles at the same time, and the code disturbances in the water droplets will also be reflected at different angles. The 40 to 42 degrees Celsius is the most intense, resulting in the rainbow we see.

When sunlight enters the water droplet, it is first refracted once, then reflected on the back of the water droplet, and finally refracted again when it leaves the water droplet, for a total of one reflection and two refractions. 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.

The colors of the rainbow are red, orange, yellow, green, blue, indigo, and purple.

Rainbow is also known as Tiangong, Rainbow, Jiang, etc., referred to as Rainbow. Rainbow is an optical phenomenon in meteorology, when sunlight hits water droplets in mid-air, the light is refracted and reflected, forming an arched colorful spectrum in the sky. Near the waterfall, on a sunny day, with your back to the sun, you can see a rainbow in the air with your back to the sun or spraying water mist.

Rainbows come in an infinite number of colors, for example, there are many subtle differences between red and orange, but for the sake of simplicity, the Warriors only use seven colors as a distinction. Sunlight is composed of 7 colors: red, orange, yellow, green, blue, indigo, and violet, and the first refraction occurs when it hits a water droplet, and due to the different wavelengths of these 7 colors, their deflection angles will be different, and then the sunlight will be decomposed into 7 monochromatic lights.

Reflected rainbow and reflected rainbow

When a rainbow appears on an object on the surface of the water, two mirror arcs from different optical paths that complement each other may appear on the surface of the water and below the surface of the water, respectively. They have slightly different names, and if the water surface is calm, the reflected rainbow will appear as a mirror image below the horizon of the water surface. Sunlight is first deflected by raindrops before reaching the observer, and then by the reflection of the water surface.

Reflected rainbows, at least partially, are often visible, even in small puddles.

When sunlight is reflected off the surface of the water before it reaches the raindrops, it may generate a reflection rainbow, which may appear above the horizon if the water surface is large enough and the entire surface is calm and close to the rain curtain. It intersects a normal rainbow at the horizon, and its arc will permeate higher in the sky because its center is above the horizon and the center of a normal rainbow is below the horizon. Due to the need for the above conditions, the reflection rainbow is very rare.

The six-colored rainbow is a common symbol of the LGBT equality movement

Red for life and orange for restoration

Yellow represents sunlight and green represents nature

Blue for harmony Purple for soul Rainbow Flag Color has always played a very important role in the expression of gay pride. During the Victorian period in England, green had always been associated with homosexuality, and purple (or more precisely, lavender) became a popular symbol of pride in the late '60s, with the fashionable term "purple power" after the Stonewall riots. And, of course, the pink triangle symbol, although it was first used by Nazi Germany to identify gay men in concentration camps, and only became a widespread symbol of homosexuality after the 80s.

However, the rainbow flag, which combines the colors of red, orange, yellow, green, blue, and purple to represent the diversity of the gay community.

The colors of the rainbow are red, orange, yellow, green, blue, indigo, and purple. Rainbow is an atmospheric phenomenon in which a large amount of water vapor is enriched in the air, and the sunlight shines at a small angle at a small angle, and the sunlight shines on the small water droplets in the water vapor to refract colorful bands. The rainbow is caused by the sunlight hitting the air and digging into the rock in the shape of a small water droplet, which causes dispersion and reflection.

Rainbows are most common in the afternoon, when the weather clears after the rain. At this time, the air was full of small droplets of dust, and one side of the sky was darker because there were 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.
