What color is the rainbow What color is the rainbow

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, cyan, blue, purple. In fact, as long as there are water droplets in the air and the sunlight is shining at a low angle behind the observer, it is possible to produce a rainbow phenomenon that can be observed. 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. Evening rainbow is a rare phenomenon that can occur at night when the moonlight is strong. Because it is difficult for human vision to distinguish colors in low light at night, the evening rainbow appears to be completely white.

The color is determined by the frequency of light, and when the rainbow appears, the frequency of the refracted light is continuously distributed, so the change of color is continuous, so strictly speaking, it is impossible to distinguish how many colors, and the 7 kinds that are usually said are just an approximate distribution. It's actually a gradient process from red to black. I don't know if I can make it clear.

After the refraction of light, it is diverged from white light into 7 colors.

The rainbow is seven colors. Rainbow is also known as the heavenly bow, rainbow, Jiang, etc., is an optical phenomenon in the meteorology, when the sunlight shines on the water droplets in mid-air, the light is refracted and reflected, forming an arch-shaped colorful spectrum on the sky of filial piety, from the outer circle to the inner circle is red, orange, yellow, green, blue, indigo, purple seven colors.

Rainbow: Sunlight is composed of 7 colors: red, orange, yellow, green, blue, indigo, and violet, and the first refraction will occur when it hits the water droplets, and because the wavelengths of these 7 colors of light are different, their deflection angles will be different, and then the sunlight will be decomposed into 7 kinds of monochromatic light; After the refracted monochromatic light reaches the back of the water droplet, it will be reflected according to the reflection law. The reflected monochromatic light will return to this side of the incident water droplet, at which point a second refraction will occur and the water droplet will still be emitted as monochromatic light.

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 rainbow is colored from the outer circle to the inner circle in seven colors: red, orange, yellow, green, blue, indigo, and purple.

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. 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 the air, the light is refracted and reflected, forming an arched colorful spectrum in the sky.

The first refraction occurs when it hits a water droplet, and because the wavelengths of these 7 colors of light are different, their deflection angles will also be different, and then the sunlight will be decomposed into 7 monochromatic lights; After the refracted monochromatic light reaches the back of the water droplet, it will be reflected according to the reflection law. The reflected monochromatic light will return to this side of the incident water droplet, at which point a second refraction will occur and the water droplet will still be emitted as monochromatic light.

Special Rainbow:

1. Moon rainbow: Moon rainbow, also known as rainbow, is a rare phenomenon that may appear at night when the moonlight is strong, because it is difficult for human vision to distinguish colors in the case of low light at night, so the rainbow looks as if it is all white jujube brother.

2. Full circle rainbow:

The full-circle rainbow is caused by the "internal reflection" of the raindrops to sunlight, because the refractive index of the raindrops and the air is different.

3. Gemini Rainbow:

Twin rainbows, which is a direct translation of Twinned Bows, they are rainbows that are born from the same root and split into two forks.

Red, orange, yellow, green, blue, indigo, purple. The rainbow, also known as the rainbow and simply known as the "rainbow", is an optical phenomenon in meteorology. When sunlight hits water droplets in the air, the light rays are refracted and reflected, forming an arched multicolored spectrum across the sky, which is common after rain.

The shape is curved, usually semicircular, and brightly colored. There are seven colors of the rainbow, from the outside to the inside: red, orange, yellow, green, blue, indigo, and oak purple.

The colors of the rainbow are red, orange, yellow, green, blue, indigo, and violet. The rainbow, also known as the rainbow and simply known as the "rainbow", is an optical phenomenon in meteorology. When sunlight hits water droplets in the air, the light rays are refracted and reflected, forming an arched multicolored spectrum on the sky, which is common after rain.

The shape is curved, usually semicircular. Brilliant colors. There are seven colors of the rainbow, from the outside to the inside, which are:

Red, orange, yellow, green, blue, indigo, purple. Many times you will see two rainbows appear at the same time, and the same will appear outside the ordinary rainbow bureau, but the darker one is the secondary rainbow, also known as "neon". The secondary rainbow is formed by the reflection of sunlight twice in water droplets.

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.
