BEAUTIFUL RAINBOW
Rainbow, must be familiar with this word right? Rainbow is a natural phenomenon that displays a very beautiful color bias.
The beautiful rainbow in the sky is spoiling our eyes. In the sky that is still cool due to raindrops, really very lull our heart to be peaceful. But have you ever wondered why that beautiful rainbow is curved?
Why not round / straight / square?
First of all the rain spots refract the visible light and make the white light separate into its seven constituent colors. Red, orange, yellow, green, blue, indigo and purple are the colors of the white color.
It turns out to see a beautiful rainbow there are various conditions. The first condition is that we must turn our backs on the light source when we see the rainbow. In this case, the source of light in question is the sun. This second requirement is the reason why the rainbow is curved ie we have to see a rainbow from an angle of about 40 degrees apart from this angle the rainbow will not look well. Therefore, the rainbow looks curved in the vast sky. And I think in this world there is no one who can see the origin and the end point of the rainbow, Because all this time we often see only the middle course.
The rainbow is one of the most beautiful natural phenomena. The rainbow happened because,
Light bend (refraction)
So, here it is. The rainbow will appear when the light is deflected when sunlight is exposed to rain water. Rainbows can be seen only in the rain and accompanied by the sun.
The next question is: Why is the rainbow color sequence always the same?
The answer is, because red light is part of the visible light spectrum that has the lowest frequency or has a long wavelength, even the longest when compared with other visible light. While purple light has a higher frequency and the shortest waves.
Therefore, why red is always top and purple at the bottom. In the middle of the two colors are in sequence: orange, yellow, green, blue, and indigo.
The rainbow usually consists of several colors like red, yellow, orange, purple and blue. Usually a rainbow appears when it's raining then rainbow appears with beautiful colors.
