Why does a rainbow appear after rain? The meaning and symbolism of the rainbow

The appearance of a rainbow means the arrival of success and happiness; "rainbow" is a positive and healthy outlook on life and lifestyle. We often say that it is lucky to see a rainbow. Generally, a rainbow appears after rain because of refraction. When sunlight is refracted on water droplets, it will produce colorful light, and the naked eye can see the rainbow.

Why is there a rainbow after the rain?

Because there are many small water droplets floating in the air after rain, when the sunlight passes through the water droplets, it is decomposed into seven color light bands of red, orange, yellow, green, cyan, blue and purple and reflected, thus presenting a colorful visual effect.

Rainbows are formed when sunlight hits small, nearly spherical water droplets in the air, causing dispersion and reflection.

When sunlight enters a water droplet, it enters at different angles at the same time, and is also reflected at different angles inside the water droplet. The reflection at 40 to 42 degrees is the strongest, causing the rainbow we see.

The visibility of the rainbow depends on the size of the water droplets in the air. The larger the water droplets, the brighter the rainbow formed. The smaller the water droplets, the less obvious the rainbow formed.

The meaning and symbolism of the rainbow

A rainbow is an optical phenomenon in meteorology. When sunlight shines on water droplets in the air, an arch of colorful spectrum forms in the sky. When the rain stops and the sky clears, the appearance of a rainbow means the end of pain and suffering, and the arrival of success and happiness.

The rainbow is the result of color balance. It also means that work and life, health and pressure, the rapidly developing society and the individual's inner self need to be balanced in order to develop.

The appearance of a rainbow means the arrival of success and happiness; "rainbow" is a positive and healthy outlook on life and lifestyle.

What is it called when two rainbows appear at the same time?

The appearance of two rainbows at the same time is a normal phenomenon. It is a phenomenon that a second rainbow can be seen outside the rainbow. However, the second rainbow is lighter than the first one. The second rainbow is generally called a secondary rainbow or a rainbow.

The rainbow appears after the rain because of refraction. When the sunlight refracts on the water droplets, it produces colorful light, and the rainbow can be seen by the naked eye.

A double rainbow can be seen because sunlight undergoes a second refraction, that is, a second refraction occurs after the first refraction, so generally the color order of the second rainbow is opposite to the first.
