What are the colors of the spectrum in order and what are the wavelength and frequency for each spectrum, which is called rainbow, and is one of the common physical phenomena in the universe, can be seen in the morning and on rainy days, and for reference here a rainbow is produced due to refraction in the ray of light emerging from the sun, and then the rain by analyzing it, so that people can see when it rains a rainbow or the colors of the spectrum, and in this article we learn what they are the colors of the spectrum in order, as well as the relationship between the visible light spectrum and the ecosystem.
How are the colors of the spectrum formed?
A rainbow is considered to be one of the most beautiful landscapes, and it is a natural physical phenomenon.A rainbow appears in the atmosphere due to the reflection and refraction of sunlight and its distribution through water droplets. Therefore, sunlight passes through through three stages until the full colors of the rainbow are formed:
- Reflection phase: the sun’s rays hit the water droplets in the atmosphere and the light is reflected from the bottom wall of the water drop; Then they are reflected to the other side and the water droplets become like small reflecting mirrors and, as a result of the droplets that accumulate in the atmosphere in the form of mirrors, they become like a large mirror reflecting sunlight.
- diffusion phase: the white sunlight is diffused in the visible colors; From where they form, as soon as they enter the water droplets, these colors come out of the droplets to be called in this case the colors of the spectrum.
- Refraction stage: The direction of sunlight changes as soon as a drop of water enters and exits it in a slight extent which varies from one color to another, for example the refraction angle of the red color differs from the orange color, because the red ray is refracted at an angle greater than the refraction angle of the orange color, the appearance of the spectrum colors depends on the degree of refraction The refraction of sunlight through the water droplets, while the apparent color depends on the wavelength.

What are the colors of the spectrum in order?
The colors of the spectrum are formed when the sun hits the raindrops, and each color of the spectrum has a wavelength, frequency and energy that differs from the other colors.In the following lines, we learn what the colors of the spectrum are in order from smallest to largest:
- the Red.
- The orange color.
- the yellow color.
- the green.
- the blue color.
- indigo;
- Viola.

How are the colors of the spectrum formed?
The colors of the spectrum are formed in such a way that the sun’s rays pass through some raindrops in the atmosphere, and a change in the direction of the light waves occurs as a result of the passage of the raindrops, causing two processes of reflection and refraction, which contribute to the occurrence of spectrum colors, and in the following lines we continue our conversation about how spectrum colors are formed:
- When light reflects off a drop of water, it returns in the direction it was born.
- Also, as with the refraction process of light, it causes the light to change direction in another direction.
- Spectrum colors are formed when invisible white light passes through raindrops.
- It refracts in different directions within the raindrop and when it reaches the other side of the raindrop.
- It is reflected in the drop instead of out of it, transforming the white light into the colors that make up the raindrop.
- The colors of the spectrum have different wavelengths.
- When white light enters a raindrop, some wavelengths are refracted more than others.
- Purple is the shortest color in wavelength, so it has the greatest amount of refraction.
- Red is the color with the longest wavelength, so it has the least refraction.
Visible light spectrum and ecosystem
The visible light spectrum is an important part of the Earth’s natural processes. For example, the earth’s food chain is heavily dependent on it and plants depend on visible light to fuel photosynthesis, the process by which they produce food, and as we provide more information on the relationship between the visible light spectrum and the ecosystem:
- Photosynthesis also produces and releases oxygen into the atmosphere, making it available for the respiration of humans and other animals.
- Studies have also shown that insufficient exposure to visible light causes brain damage and emotional illness in humans.
- Conversely, excessive exposure to visible light can damage the eyes and skin.
- So, enjoy the wonders of visible light every time you see it.

We came to the conclusion of the article, in which we got acquainted with what the colors of the spectrum are in order, and it is one of the physical phenomena that occur on Earth, and we explained its role in the ecosystem, and how these colors are formed , as we have explained to you the wavelength and frequency for each of the seven color spectra.
