Gas discharge refers to the process where an electric current passes through a gas, leading to ionization and the emission of light. This phenomenon is fundamental in various applications, including neon signage, plasma displays, and fluorescent lighting, due to its ability to produce visible light and other electromagnetic radiation.

Ionization is the process in which an atom or molecule acquires a negative or positive charge by gaining or losing electrons, often in response to energy input. This process is fundamental to various fields such as chemistry, physics, and environmental science, influencing phenomena like conductivity, chemical reactivity, and atmospheric dynamics.

Fluorescent lighting is a type of lighting technology that uses electricity to excite mercury vapor, which in turn produces short-wave ultraviolet light that causes a phosphor coating on the inside of the bulb to glow. This type of lighting is known for its energy efficiency and long lifespan compared to incandescent bulbs, making it a popular choice for commercial and industrial applications.

Visible light is the portion of the electromagnetic spectrum that is detectable by the human eye, encompassing wavelengths from approximately 380 to 750 nanometers. It is responsible for the perception of color and is a fundamental component in various technologies, from photography to optical communications.

Electromagnetic radiation is a form of energy that travels through space at the speed of light, encompassing a wide range of wavelengths and frequencies known as the electromagnetic spectrum. It includes visible light, radio waves, X-rays, and more, each with unique properties and applications in fields like communication, medicine, and astronomy.
