The sky mirror appears in the Forbidden City after the rain. What is the scene like?

On September 1st, a photography enthusiast used a mirror to create a "mirror of the sky" scene in the Forbidden City. The mirror reflected the blue sky, white clouds, and jade buildings, as if he were in a fairyland on earth. The originally solemn Forbidden City has become a little more intimate.

This phenomenon is based on the principle of specular reflection, which is knowledge learned in our junior high school physics textbooks. Specular reflection refers to the reflection of reflected waves, such as electromagnetic waves, sound waves, water waves, etc., with a certain direction; the angle between the direction of the reflected wave and the normal line of the reflection plane is the reflection angle, and the direction of the incident wave and the normal line of the reflection plane The angles between the lines, that is, the angles of incidence, are equal, and the incident wave, reflected wave, and plane normal are all in the same plane.

In addition to specular reflection, there is also diffuse reflection. Diffuse reflection refers to a physical phenomenon in which light projected on a rough surface is reflected in all directions. When a beam of parallel incident light hits a rough surface, the surface will reflect the light in all directions, causing the direction of the reflected light to be irregular, which is called diffuse reflection.

The Forbidden City, also known as the Forbidden City, is the royal palace of China during the Ming and Qing Dynasties. It is located at the center of Beijing's central axis. The Forbidden City covers an area of ??720,000 square meters and can be divided into the former dynasty and the inner court. The former dynasty is centered on the three main halls - Taihe Hall, Zhonghe Hall, and Baohe Hall. It is the place where the emperor and his ministers held court affairs and held grand ceremonies. The inner court is centered around Qianqing Palace, Jiaotai Palace and Kunning Palace. It is where the emperor, concubines and princes sleep. The Forbidden City is one of the largest and best-preserved wooden structure ancient buildings in the world. It is a national 5A-level scenic spot.

The Forbidden City is surrounded by city walls, and there is a moat outside the city walls, forming a perfect defense system. Stepping into the palace from the Meridian Gate, looking at this magnificent palace, you can't help but feel the beauty in your heart. If you come to Beijing for tourism or business, you might as well take a look at the Forbidden City and feel the architectural beauty and endless charm of the Forbidden City.
