"I understand reflection, then what is refraction?"

"If you insert the chopsticks into a bowl filled with water, the chopsticks look curved, which is the refraction phenomenon." Weiwei.

"I seem to understand. Then, why is the sunlight reflected on the moon by the Earth's atmosphere? Is it necessary to be red? Is it not possible to have other colors?" Xinxin continued to ask.

He was slightly amused and said, "Then what color do you want the moon?"

"Red, orange, yellow, green, blue, purple, and colorful rainbow colors are like the colorful jadeite of the millet, which can emit colorful light, so beautiful and beautiful."

At this time, he looked up slightly at the red moon, and suddenly sighed and said, "I also hope that the moon can be colorful so that it will be more beautiful. But how can everything be as wished?"

Xinxin smiled and said, "Actually, the white moon is the most beautiful, just like a glowing night pearl, crystal clear."

"Yeah." Nodded slightly, "Nature's original is the best."

...

The cause of the red moon is only a preliminary and not in-depth discussion. The essential cause is not complicated. When the full-color sunlight enters the earth's atmosphere, the wavelength of the yellow, green and blue light waves is easily absorbed by the atmosphere. Because of the long wavelength, the red light is not greatly affected by the scattering of the atmosphere. After entering the atmosphere, it can even pass out and finally refracted to the moon behind the earth. This part of the red light makes the moon look red.

The red moon can be divided into broad and narrow meanings. The broad red moon may occur at any time, but it is too random and is not very obvious. So when we look up at the moon, we rarely see the red moon. The narrow red moon occurs during the total eclipse of the moon, and it is as red as burning charcoal. As long as it is not a blind man, it can be seen. Today is definitely not the day of the total eclipse of the moon. Now the moon is beginning to turn red, and it is not very obvious for the time being, so we can only blame the so-called broad red moon.

Is today's moon really a broad red moon?

When the Breakers thought so and explained this to calm the people's hearts, Li Erdan was wondering in her heart, giving the third answer, the moon might really "burn", and the engines of hundreds of planets emerged.

In fact, Li Erdan just thought about it this way and was not very sure. Besides, the moon is not very red at this moment!

The frowning little girl was questioned continuously by Xinxin, and was amused and laughed, and she was full of joy.

Yuting, who is sad, is accompanied by her son and talks to Ania from time to time. At least she doesn't seem very sad and sad on the surface.

The two sisters Nie Xiaoying and Yanzhi sat together to eat mooncakes, snacks, and drink delicious wines. They were adapting to life in the flower world, and their melancholy faces could not be reflected in their faces. We have reason to think that they were happy at this moment.

Nie Xiaoying has reason to be happy because there is more fun in the world than when she was a little fox. However, she lives in spending time and sometimes envies mandarin ducks and butterflies.

Yanzhi originally lived in the Western Paradise, where the dogma was very strict and it was not a place to live. Now he has come to the world. Although he has not yet cultivated a relationship with Li Erdan, the reincarnation of the Dragon Arhat, she is temporarily satisfied and happy.

If you want to say the saddest and most pitiful one, it is Xiaoqing.

Xiaoqing is so pitiful. She sat on the floor with her legs and knees in her arms, her eyes moistened for a while. Li Erdan took a biscuit and sat down in front of her, saying, "Dear, what do you think?"

Xiaoqing didn't answer.

"Eat a biscuit!" Erdan said again.

"No appetite." Xiaoqing.

"Man is iron rice and steel. How can I not eat anything?" Li Erdan said, and handed the mooncake to Xiaoqing's mouth. "This mooncake was given by Chief No. 1. It's tribute, and I can't buy it on the market. I'm not willing to eat it myself, so I'll leave a piece for you."

When the smell of the mooncakes, Xiaoqing suddenly felt sick and even started to retching. She said dissatisfiedly: "What kind of broken mooncake are you? Why are you so unpleasant?"

"It smells bad? Is there anything? I'll go, it smells pretty fragrant, it tastes even more fragrant." Erdan said, and then handed the mooncake to Xiaoqing's mouth.

This time, Xiaoqing grabbed the mooncake and threw it aside. For some reason, her stomach felt very uncomfortable, and she vomited waves after wave of dry retching, and she vomited all her tears, and she couldn't stop it.

"What's going on with you? Why do you relapse when you smell the mooncake?" Li Erdan said anxiously.

"I don't know, I just want to vomit when I smell your mooncake, but I can't vomit, so I can only spit out the water. I feel so uncomfortable. Please bring me a bottle of water to rinse my mouth." Xiaoqing was still retching while speaking.

Li Erdan hurriedly went to get water for Xiaoqing, and the rest of the people present surrounded Xiaoqing.

Girl Nie Xiaoying said, "Xiaoqing, you won't get pregnant, right? I heard that when you human girls are pregnant, they will urge to vomit when they smell greasy things."

You human girls? Why do girls Nie Xiaoying say you human girls?

After swinging, everyone's eyes gathered on Nie Xiaoying.

Weiwei said to Xiaoying: "Xiaoying, are you not a human?"

Xiaoying knew that she had broken her promise and stammered: "I, I, of course, I am a human, why am I not a human?"

"Then why do you say 'you human girls'? It's just like you are not human?" Weiwei.

The girl Rouge quickly smoothed out the topic and said, "I can take my pulse and ask me to take Xiaoqing's pulse. I can feel it from the pulse or not."

Yanzhi and Xiaoying have lived with everyone for a while, but in everyone's eyes, they were full of fascination and mysterious things. Xiaoying can take her pulse, but everyone really doesn't know.

Xinxin said, "Take the pulse and take the pulse quickly! If Sister Xiaoqing is pregnant, that would be great, Shushu will definitely be very happy."

When Li Erdan brought a glass of water from the house, Yanzhi was taking Xiaoqing's pulse.

"I'll go, what are you doing together?" Li Erdan asked in confusion.

Xiao Xinxin was very cute and booed to Li Erdan, "Shhh, Sister Xiaoqing is likely to be pregnant, Sister Yanzhi is taking her pulse and breaking her pregnancy."

"Pregnant?" Li Erdan was arrived by Lei, "Just kidding, how could he get pregnant?"
