Definition
- Noun:
- An electrical discharge accompanied by ionization of surrounding atmosphere: A luminous phenomenon resulting from the flow of electric current through a gas, causing the gas to ionize and emit light. This is a specific type of plasma discharge.
Usage Examples
- Noun:
- The scientist studied the faint electric glow inside the experimental vacuum tube.
- In the dark room, the neon sign emitted a steady, colorful electric glow.
Advanced Usage
- Technical Context: Often used in physics and engineering to describe the visible light from a non-thermal plasma, such as in glow discharges, neon lights, or certain types of electrical corona effects.
- The electric glow observed in the Geissler tube is a classic demonstration of gas discharge physics.
Variants and Related Words
- Glow discharge (n): A type of plasma formed by the passage of electric current through a low-pressure gas; it is the physical process that often produces an "electric glow."
- The operation of some plasma televisions relies on the principles of a glow discharge.
- Corona discharge (n): An electrical discharge brought on by the ionization of a fluid surrounding a conductor; it can sometimes produce a visible glow.
- A faint corona discharge, or electric glow, was visible around the high-voltage power line.
Synonyms
- Luminous discharge: An electrical discharge that produces light.
- Gas discharge: The flow of electric current through a gas, often resulting in emission of light.
Related Phrases
- To emit a glow: To produce or give off a steady light.
- The argon gas began to emit a soft blue glow when the voltage was applied.
