Why does the arrangement of rainbow colors never change?

Did you know that the arrangement of the beautiful colors of the rainbow is not accidental and behind it is a science? Physics and photography explain this phenomenon.

Rainbow is one of the most beautiful natural phenomena that always appears in the same way as familiar red, orange, yellow, green, blue, indigo and purple. But have you ever wondered why these colors are always constant and not changing? The answer to this question lies in the science of physics and photography.

The secret

The colors of the rainbow always appear in a special order, as this is determined by the wavelength of light. The red light, with a longer wavelength, is placed in the outermost part of the rainbow; While purple light is seen with the shortest wavelength in the most internal part.

This arrangement of the colors is remembered by the Roygbiv or Roy G. BIV, which stands for red (red), orange (orange), yellow (yellow), green (green), blue (blue), indigo and purple ( Is Violet).

The rainbow is formed when the sun’s light hits the water droplets in the air and the white light breaks down into a range of colors. This phenomenon is due to the failure of the refraction. When sunlight enters the water drops, its speed decreases and its path changes.

This redirection causes the light to decompose into different colors. Each color is broken at a different angle, and eventually these colors come together to form the rainbow that we see.

Isaac Newton’s role in understanding the rainbow

Isaac Newton was the first to discover the scientific reason for the formation of the rainbow. Using a prism, he decomposed white light into the color spectrum and showed that white light is made up of different colors.

Newton also decided to put the color of the indigo as a separate color in the rainbow, though it is hardly recognizable from blue and purple. He did so to bring the number of colors to seven because he believed that it was in line with music notes.

How do the charters work?

The charters act just like water droplets in the rainbow. When white light enters the charter, its speed decreases and its path changes. This process, which is called dispersion, causes light to decompose into different colors.

The red light with a longer wavelee has the least failure; While the shorter purple light experiences the most failure.

The diagnosis of colors with the human eye

The human eye is capable of detecting the visible spectrum of light using conical cells. These cells are sensitive to different wavelengths of light and regard each wavelength as a particular color. Red light with a wavelength of about 2 nm is on one side of the spectrum; While purple light with a wavelength of about 5 nm is seen on the other side of the spectrum.

Some colors, such as pink, gray and brown, are not seen in the rainbow; Because these colors are created by a combination of different light waxes and do not exist as pure spectral colors. For example, the pink color comes from the combination of red and purple light that is at the two opposite ends of the spectrum.

The arrangement of rainbow colors never changes; Because this is based on light wavelengths and physics laws. From red light to the longer wavelength to the shorter purple light, each color has a constant place in this beautiful phenomenon. The next time you see a rainbow, remember that this stunning show is the result of precise coordination of light, water and the rules of nature.
