China Photography after Rain

On September 1 day, a photographer created pictures with a mirror in the Forbidden City. Mirror of the sky? At the scene, the mirror reflected the blue sky and white clouds, and the Qionglou Yuyu seemed to be in a fairyland on earth, which brought the solemn Forbidden City closer.

This scene is based on the principle of specular reflection, which we learned in junior high school physics textbooks. Specular reflection refers to reflected waves, such as electromagnetic waves, or acoustic waves, water waves, etc. , with a certain reflection direction; The included angle between the reflected wave direction and the normal of the reflecting surface is the reflection angle, the included angle between the incident wave direction and the normal of the reflecting surface is the same as the incident angle, and the incident wave, the reflected wave and the plane normal are all in the same plane.

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

The Forbidden City, also known as the Forbidden City, is the royal palace in China during the Ming and Qing Dynasties, located in the center of the central axis of Beijing. The Forbidden City covers an area of 720,000 square meters and is divided into the former dynasty and the imperial court. The former dynasties were centered on the Hall of Supreme Harmony, the Hall of Zhonghe and the Hall of Baohe, where emperors and courtiers held state affairs and held ceremonies. The Imperial Palace, centered on Gan Qing Palace, Jiaotai Palace and Kunning Palace, is the place where emperors, concubines and princes sleep. The Forbidden City is one of the largest and best-preserved ancient wooden buildings in the world, and it is a national 5A-level scenic spot.

There are walls around the Forbidden City and moats outside the walls, forming a perfect defense system. Walking into the palace from the meridian gate, looking at this magnificent palace, the beauty inside is shocking. If you come to Beijing for tourism or business, you might as well take a look at the Forbidden City and feel its architectural beauty and infinite charm.
