A rainbow right? A rainbow, right?

A rainbow" is okay. However, it is more appropriate and more commonly used to use the term "a rainbow". The rainbow, also known as the rainbow and simply known as the "rainbow", is an optical phenomenon in meteorology.

<> "Incorrect. The rainbow is formed by the refraction of sunlight through raindrops or water droplets, so it exhibits a band-like spectrum of seven colors.

A rainbow is not right, it is generally said to be a rainbow.

No, (reference, documentation).

A rainbow is an optical phenomenon formed by the refraction and reflection of sunlight in water droplets, not an actual object.

The rainbow is not one, it is colorful.

"A rainbow" is fine, but it is more appropriate and more common to use "a rainbow". Rainbow, also known as rainbow, 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 in 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.

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 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; 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.

A rainbow.

Word]: Rainbow.

Pinyin]: cǎi hóng

Zhuyin]: Explanation]: The arc-shaped colored band of light in the sky where sunlight and water vapor are reflected.

Example sentences]: 1) After the rain, a rainbow appears in the blue sky, red, orange, yellow, green, cyan, blue, purple, various colors are intertwined and shine together, like a golden bridge, majestic across the sky.

2) The rainbow is so beautiful and moving, from one end of the earth to the other, like a band of flowers woven on the azure skirt.

Many books say "a rainbow." ”

In fact, there is nothing wrong with these two titles, no matter how you call them, they are all right. Because people often call the rainbow a bright rainbow, or a beautiful rainbow bridge.

"A rainbow" is incorrect, it is not properly matched, and the correct way to say it is "a rainbow".

Incorrectly, the adjective of a rainbow uses a strip to describe it, it should be a rainbow. A tall building.

There is a rainbow and a rainbow. After the rain, rainbow bridges sometimes appear on the horizon (in the distance), which are dazzling. Sometimes it is fragmentary, or the left is on the ground, or the right is pressed on the ground.

Yes, yes, or there is a gap between the left and right sides. I think that in addition to the rainbow bridge, the intermittent can be called a rainbow.

"A rainbow" is fine, but it is more appropriate and more common to use "a rainbow". A rainbow: A strip refers to an elongated shape, and the shape of a rainbow is elongated.

It can also be said that a rainbow: the Tao has the meaning of lines, and the measure word Tao is used here because the rainbow also has lines.

It can also be said that a rainbow: the quantifier piece has the meaning of referring to the area, range, scene, mind, etc., or the thing that is a piece, and the piece is used here because the rainbow has an area and scope.

Reasons 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 a water droplet, it is incident at different angles at the same time, and it is reflected at different angles within the water droplet.

Among them, the reflection of 40 to 42 degrees is the most intense, resulting in the rainbow we see. When this reflection is caused, sunlight enters the water droplet, is refracted once, is reflected on the back of the bent of the water droplet, and then refracted again when it leaves the water droplet, for a total of two refractions after one reflection and two refractions. <>

A rainbow.

Rainbow, also known as Tiangong, Tianhong, Jiang, 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 colorful spectrum on the sky, from the outer circle to the inner circle in red, orange, yellow, green, blue, indigo, purple, and wear eight colors.

There will be a dim second rainbow on the outside of the main rainbow, which is the neon, which is produced by the two reflections and two refractions of sunlight within the raindrops. Even darker is the third rainbow, and even the fourth rainbow is rising.

Hello dear <> my answer is as follows, please be patient and take a look at the <>

It's a rainbow. People will say a rainbow because the rainbow is shaped like an arc in the sky, and as a colorful scene, it is more appropriate to use a quantifier like "one" to describe it. Formation of the rainbow:

Rainbows are formed by the reflection, refraction, and internal reflection of water droplets from the sun shining on the air on a rainy day, producing light that is different in color. The color sequence used in the rainbow is red, orange, yellow, green, cyan, blue, and violet, which is also due to the different wavelengths of these colors and the refraction at different angles. In addition to our common rain rainbows, hail pure also has glow rainbows and moon rainbows.

Among them, the glow rainbow is formed in ice crystals or water droplets in the clouds, while the moon rainbow is formed in the action of moonlight or light under the moon. Rainbows have different meanings in different cultures and legends.

The rainbow is not a single physical object, it is an optical phenomenon caused by sunlight passing through water droplets. Theoretically, everyone might see a rainbow differently because it could be based on the observer's position and light, and the rainbow could also be because different kinds of water droplets exhibit different spectrums. Therefore, we cannot say that there is "a rainbow", because everyone may see it differently.

Rainbows are created by sunlight passing through water droplets, which then refracted and reflected, causing different spectral separations. The most common form of the rainbow is a V-shaped arc. It consists of seven colors: red, orange, yellow, green, blue, and violet, and the colors are arranged in order from longest to shortest wavelength.

Due to changes in the shape, size, and position of the water droplets, each person may see a slightly different rainbow, so different people may see the same rainbow.

At the same time, there are places where a double rainbow may form, which is caused by the light reflecting twice inside the water droplet. Such a rainbow is made up of an outer arc and a weaker inner curved another V-shaped arc. Front beam.

In conclusion, the formation of a rainbow is complex, and everyone may see it slightly differently. There is no such thing as a "right answer" for a rainbow, so there is no difference in saying that there is a "rainbow". <
