From a physics point of view, light was a natural phenomenon. It was both an electromagnetic wave and a photon current. It had wave-particle dualism. In terms of the optical spectrum, the spectrum of visible light was 380 - 780 nanometres. This was only a part of the electromagnetic spectrum. There were also non-visible light such as infrared light, infrared light, and X-ray. From an energy point of view, the photon energy was related to the frequency of electromagnetic waves (E = hv, h was Planck's constant, v was the frequency). In the photon effect, the collision of a photon with energy greater than the binding energy of the shell electron and the atomic electron of the material could cause the electron to escape and become a photoelectron. From the perspective of word-making and cultural meaning, the word "light" in the oracle bone inscriptions was composed of flames and curled people, indicating that the inner light of a person could illuminate the heart, while the word "bright" was composed of windows and moonlight, representing external light. The word "bright" reflected the wisdom of Chinese word-making, which meant the unity and harmony of inner clarity and external brightness. In addition, from a historical point of view, the law of light reflection was already well-known in the era of ancient Greece, while in ancient China, as early as the Warring States Period, Mozi discovered the law of light reflection and established an optical system. At different stages of scientific development, people had different understandings of the nature of light, such as "wave theory" and "particle theory." Light sources were objects that could convert other energy into light energy and emit light. There were natural and man-made.
