how is a rainbow formed

how is a rainbow formed Rainbows are formed by refraction and reflection when light rays pass through the water droplets. Light rays that move inside an environment are either reflected in the same environment when they are encountered in another environment or are broken into the other environment. In the case of reflection, the rotation angle of the light to the intermediate surface is the same. But the angle changes during breakage. The refractive angle is determined by the refraction indices of the environments. Moreover, different color rays are broken in different angles because the refractive index varies depending on the wavelength of the rays. For example, white light is a combination of rays of different wavelengths. When the rays of different wavelengths are passed through a prism, they break at different angles (once unplugged when entering the outlet). Thus, the white light leaves the lights in the different colors that compose itself. The refractive angle is the smallest for the largest, purple color for red color. The formation of the rainbow is a process that is very similar to the separation of light as it passes through the power outlet.

Light rays come into the water drops and break out once they are broken. They can also reflect several times in the drops. When the rays are reflected once before they leave the drops, the colors are composed of rainbows, which are lined with red, orange, yellow, green, blue, navy, purple. If the rays are reflected twice, the colors are reversed. With the reflection of light rays two or more times, rainbows can occur. However, such rainbows are usually very pale.

Rainbows actually consist of a full circle, but the sun must not have risen more than 40 degrees above the horizon in order to see the rainbow. Therefore, when viewed from the surface of the Earth, rainbows appear in half a circle form. But when you look through a high mountain or a plane flying high, you can see rainbows in the form of a full circle.
