gas discharge physics

Gas discharge physics refers to the process by which electricity flows through a gas, creating visible light and other effects. When a high voltage is applied, gas atoms can become ionized, meaning they lose electrons and form charged particles. This ionization enables the gas to conduct electricity. As the charged particles move, they collide with neutral gas atoms, exciting them and causing them to emit light of various colors. Common examples of gas discharge include fluorescent lights and neon signs, where this phenomenon creates the bright, colorful displays we often see in everyday environments.
