The reflection and refraction of light are the two most basic phenomena in the field of light. The Reflection of Light When light is shot from one medium to another, some of the light will be reflected back while the other part will pass through. In the process of reflection, the refraction index of light and the medium is proportional to the inverse ratio of the incident angle. The law of reflection states that when a ray of light is shot at a medium at a normal angle to the surface of the light, the angle of the light reflected on the reflective surface is equal to the angle of reflection. This law was known as the law of reflection, which meant that light would maintain its direction and intensity during reflection. The reflection of light can occur on the surface of water, glass, walls, etc. The wave length and frequency of light will not change, so we can observe the interference and refraction of light during the reflection process. Refraction of Light When light rays are shot from one medium to another, some of the light rays will penetrate and some will be reflected back. The relationship between the incident angle and the refraction angle in the refraction process is different from the relationship in the reflection process. The law of refraction states that when a ray of light is shot at a medium at a normal angle to the surface of the incident, the angle of the incident and the angle of refraction are equal, but the angle of refraction is smaller than the angle of the incident. This law was called the law of refraction, which meant that light would change direction and intensity during refraction. The refraction of light can occur on the surface of air, water, etc. The wave length and frequency of light will change, so in the process of refraction, we can observe the phenomenon of light refraction and reflection interference.

The seventh volume of Qing Yu Nian mainly described Fan Xian's negotiations with the Qing Emperor, his plan to assassinate the Qing Emperor, and his parting with Chen Pingping. Fan Xian had experienced all kinds of events, including successfully finding a fair chance to fight, escaping the Jingdou battle, joining forces with the Iron Triangle, and so on. The details included Fan Xian's negotiations with the Qing Emperor, his success in finding a fair chance to fight, his failure to assassinate the Qing Emperor, his escape from the Jingdou battle, and his alliance with the Iron Triangle.

I'm a fan of online literature, and I can't provide the answer to the first volume of the seventh grade novel. My knowledge is limited. If you need an answer, please let me know. I'll do my best to help.

Historical reading notes were meant to enrich one's knowledge and reading ability through in-depth study and understanding of historical events, characters, culture, and so on. Here are some suggestions from history reading notes: 1. Reading general history: General history refers to the history of each dynasty and period. It can help readers understand the context and trend of historical development, grasp the order and significance of historical events. I recommend reading General History of China and other general history books. 2. Read professional history books: For professional history books of a certain field or period, you can study the characters, events, culture, etc. in depth to understand the basic concepts and development process of the field or period. It is recommended to read professional history books such as Records of the Historian and Zi Zhi Tong Jian. 3. Read books that combine novels and history: Some novels have certain connections and similarities with historical events. By reading such books, you can better understand and remember historical events. I recommend reading novels that combine history, such as One Hundred Years of Solitude and Romance of the Three Kingdoms. 4. Take notes: During the reading process, you can record some important events, people, cultures, etc. to help deepen your understanding and memory. At the same time, he could record the insights and thoughts in the reading process as material for future thinking and writing. 5. Read more: History is a broad field. The more you read, the more you can understand historical events and cultures. It can also enrich your own thinking and vision. It is recommended to read all kinds of historical books and articles, including novels, news, magazines, etc.

There were a total of 12 volumes of the novel," Celebrating the Years ". The seventh volume was called " City of White Frost ", and the twelfth volume was called " Wind Rising from Apple Dust ". This novel used Fan Xian as the main character and told the story of his turbulent life in Qing Kingdom. Fan Xian had a distinct personality and was hot-blooded and passionate. Through experiencing a series of events such as family grudges, Jianghu disputes, and court politics, he showed his growth and struggle.

They make history more engaging. For example, instead of just reading dry facts about the Civil War, a historical fiction book might tell a story from the perspective of a young soldier or a slave. This makes the events more relatable.

Seventh-grade clergymen referred to the hierarchy of clergymen in the Church. During the 1947-1972 Holy Control period, the Roman Roman Church divided the priesthood into seven levels: First Class Clerics, Second Class Clerics, Third Class Exorcists, Fourth Class Deacons, Fifth Class Assistant Deacons, Sixth Class Deacons, and Seventh Class Priests (including priests and bishops). After 1972, the Church abolished the seventh-grade priesthood system and implemented a three-level priesthood system consisting of deacons, priests, and bishops. Other low-level positions could be taken up by laymen.

The Ming Dynasty was a dynasty in Chinese history that spanned from about 1368 to 1644. The achievements of science, technology, architecture, and literature during this period were very remarkable. In terms of science and technology, there were many inventions during the Ming Dynasty, such as gunpowder, the compass, and paper-making. One of the most famous was the Ming Dynasty scientist Xu Xiake's invention of the " glider ", a machine driven by gunpowder that could be used for flight and exploration. In addition, the Ming Dynasty also produced many advanced weapons and military equipment such as firearms, bows and arrows. In terms of literature, there were many outstanding works in the Ming Dynasty, such as Dream of the Red Chamber, Water Margins, Journey to the West, etc. These works reflected the social style and people's lives at that time and were regarded as classics in the history of Chinese literature. During the Ming Dynasty, technological buildings were also very developed. For example, the Forbidden City in Beijing, the Temple of Heaven and other buildings were built during this period. These buildings used a variety of advanced designs and techniques such as glazed tiles, red walls, yellow tiles, brick structures, etc. They had very high artistic and historical value.
