What season will there be rainbows?

Question 1: In what season do rainbows often appear? Rainbows usually appear in summer and autumn, and there are more rainy seasons, because the sun appears soon after the rain, and rainbows are refracted by sunlight and water droplets in the air after the rain.

Rainbow, also known as rainbow, is an optical phenomenon in meteorology. When the sun shines on the water droplets in the air, the light is refracted and reflected, forming an arched color spectrum in the sky, which is a common phenomenon after rain. Curved, usually semicircular. Rich and colorful. The most common sayings about seven-color light in East Asia and China (in descending order of wavelength) are red, orange, yellow, green, blue, indigo and purple.

Scientific explanation:

Rainbow is an optical phenomenon in meteorology. When sunlight hits the raindrops in mid-air, the light is refracted and reflected, forming an arched color spectrum in the sky.

Rainbow is a natural phenomenon, which is caused by the reflection and refraction of sunlight when it hits water droplets in the air.

Natural principles:

Rainbow is formed by the dispersion and reflection of sunlight on small round water droplets in the air. When sunlight enters a water drop, it will be incident at different angles at the same time and reflected at different angles in the water drop. Among them, the reflection of 40-42 degrees is the strongest, forming a rainbow that people see.

In fact, as long as there are water droplets in the air and the sun shines behind the observer at a low angle, an observable rainbow phenomenon may occur. Rainbow usually appears in the afternoon, when the rain clears. At this time, the air is less dusty and full of water droplets, and one side of the sky is dark because of rain clouds. However, observers can see the sunlight without being covered by clouds above or behind them, so rainbows are easier to see.

The appearance of rainbow is related to the weather change at that time. Ordinary people can infer whether it was sunny or rainy from the position where the rainbow appeared in the sky. When there is a rainbow in the east, it is not easy to rain locally, but when there is a rainbow in the west, it is likely to rain locally.

The visibility of rainbow depends on the size of water droplets in the air. The bigger the water drop, the brighter the rainbow, and the smaller the water drop, the less obvious the rainbow is. Generally, in winter, the temperature is low, there are few water droplets in the air, and there is less chance of rain, so there is generally no rainbow in winter.

Question 2: What season is the weather and when will the rainbow appear in a day? Summer afternoon

Rainbow is a natural phenomenon formed by the refraction of light, similar to neon, but different from rainbow in color arrangement.

Therefore, rainbows usually appear after summer showers, when the water vapor is transpiration and the sun is shining. Strong sunlight and transpiration of water mist are indispensable. So there may be one around the waterfall.

If you want to see a rainbow in the city, the easiest way is to spray water into the sky with a watering can in a sunny place, spray more, and then you can see a clear rainbow from a certain angle, but it doesn't last long and it's not easy to be clear.

There is another way, you can go to the street and find a lawn that is being watered. When the sunshine is good, there will be a clear and lasting rainbow, which is very beautiful.

The rainbow can be seen clearly in the distance, but it can't be seen near. Good things are always like this, and you can only see them from a distance.

Question 3: When will the rainbow appear in the season? Summer, especially in the evening after the rain.

Question 4: When does the rainbow appear? summer In summer, the sun is located in the Tropic of Cancer, near China, and its temperature is high. When it shines on the sea surface, more water will be gasified, and the cold, warm, dry and wet airflow will be transmitted between the ocean and the mainland, resulting in rainfall, so there will be more rain in summer. Rainbow is formed by the scattering and reflection of sunlight on small round water droplets in the air. When sunlight enters the water drop, it will be incident at different angles at the same time and reflected at different angles in the water drop. The reflection of 40 to 42 degrees is the strongest, which produces the rainbow we see.

Question 5: Do Pisces and Gemini match? Why don't you trust your feelings?

As for the value of those remarks, they are not all artificial.

Believe in yourself rather than others! !

I support you, my friend!

Question 6: When is the easiest time to see the rainbow? Rainbow is the easiest to see after rain. Because sunlight shines on water vapor in the air (there is more water vapor after rain), water vapor reflects sunlight, so rainbows often appear on the horizon ―― always in the opposite direction to the sun.
