LIGHT SYSTEMS
Light arises from the property of electromagnetic radiation within a certain part of the electromagnetic spectrum. The word usually represents 'visible light' that is visible to the human eye and is responsible for the sense of sight. Visible light is generally defined by having wavelengths in the range of 400-700 nanometers (nm), between infrared (those with longer wavelengths) or ultraviolet (those with shorter wavelengths). These wavelengths roughly correspond to a frequency range of 430-750 terahertz (THz).
Its Place in Our Lives
Historically, light sources for humans range from ancient campfires to kerosene lamps. Since the discovery of electricity and the development of power systems, electric lighting has effectively replaced fire. The term light sometimes refers to electromagnetic radiation of any wavelength in its original sense, regardless of whether it is visible, including gamma rays, X-rays, microwaves, and radio waves, and light. Since the existence of humankind, from ancient times until the 18th century, light was only known as 'visible light' and took its place in our lives. In the 18th century, studies on light did not include any scientific studies other than the separation of visible daylight (white light) into its spectra, the formation of light interference patterns, optics, mirror reflection experiments, and measuring its speed. Since the 19th century, extensive studies have been conducted on the electromagnetic spectrum, including X-rays (Roentgen rays) and other electromagnetic radiations such as radio waves and ultraviolet rays, and they are taking their place in our daily lives. We benefit from radio and TV broadcasts, radio telescopes, infrared telescopes, night vision systems, laser communication systems, laser metal cutting, medical advancements, and beam and light system technologies. It has revolutionized the field of medicine, opened up international communication via the internet, and continues to be a focal point for the interconnected cultural, economic, and political aspects of global society. For centuries, light systems have transcended all borders, including geography, regardless of gender, age, and culture, and have also become a unique position in education and other fields. It carries an important future by emphasizing the cultivation of an engineering and innovative generation by directing bright young people towards optics and photonics, and by ensuring the same dedication in product quality.
