How does the rainbow appear?

Such phenomenon as a rainbow fascinates not onlychildren, but also adults. Probably, for this reason, people ask themselves how the rainbow appears. The fact is that an ordinary solar ray or a ray of light from a lamp, conceals a multitude of colors. At first glance, they are invisible, but if combined with drops of water or any other moisture, they change, revealing all their colorful sides. This is the answer to the question of why the rainbow is multicolored, you can see more about it here: "Why is the rainbow multicolored?".

If physics was one of your favoritessubjects, you can refer to it in search of an answer to the question of how the rainbow is formed. From the school course you can recall the section of optics. The first two components of the rainbow are light and water. What is light? This is electromagnetic radiation having a small wavelength, and accordingly, each color is a certain length. To get all the colors that make up the rainbow, you need to pass a white ray through a drop of water to break it and get seven colors of the rainbow. We can conclude that the rainbow is a simple ray of light refracted in drops of water.

The appearance of the rainbow affects one factor - wetair. Each drop that moves chaotically in space is a prism that refracts light, creating different colors. To have a rainbow, there should be rain nearby or be a fog. Particles of light, falling into a drop of water, create a projection that can be seen in the sky in the form of a rainbow-arc. In order for the rainbow to be visible, the drops must necessarily be in front of the sun's rays. This is the answer to the question of how the rainbow turns out.

Perhaps you have noticed a phenomenon such as a doublerainbow. This is not a complete deception. The fact is that one rainbow can be seen quite clearly, the second blurs in the haze. A ray of light is broken several times, but from different angles. The projection appears on the horizon twice, just the opposite. Rather, the rainbow is in the same direction, and the colors are opposite. Therefore, if you are interested in the question of why a rainbow appears in a double form, this is the answer. Take a closer look at the second multi-colored arc and you will be able to confirm it yourself.
