What is the energy pathway for fluorescent light?
In a fluorescent light bulb, electricity passes through a gas (such as mercury vapor) causing it to emit ultraviolet light. The ultraviolet light then strikes a phosphor coating on the inside of the bulb, causing it to emit visible light. This conversion process is more energy-efficient compared to incandescent bulbs.
How do bubbles emit light?
Bubbles can emit light when they are filled with a gas that is excited by an external energy source, such as sound waves or ultraviolet light. This excitation causes the gas molecules to release light photons, which creates the glowing effect seen in some bubbles.
How is electricity turned into light?
Electricity is turned into light through a process called incandescence or electroluminescence, depending on the type of light source. In incandescence, an electric current passes through a material such as a tungsten filament in a light bulb, causing it to heat up and emit light. In electroluminescence, an electric current is passed through a semiconductor material in devices like LEDs, which emit light as the current flows through them.
Does the gas stove emits light explain?
Yes, gas stoves emit light in the form of a blue flame when the gas is ignited. This light is a result of the combustion process of the gas with oxygen in the air, creating a visible flame.
Can gases emit radiation?
Yes, gases can emit radiation. When a gas is heated, it can emit thermal radiation in the form of light. Additionally, certain gases can absorb and emit specific wavelengths of radiation, such as in the process of fluorescence or phosphorescence.
Do atoms in an incandescent gas absorb or emit light?
Atoms in an incandescent gas emit light. When the atoms are excited by a heat source, they release energy in the form of photons, which we perceive as visible light. This is the process that creates the glowing effect in incandescent gases.

What is the gas Argon used for?
Incandescent light ,
What is an incandescent bodies of gases called?
An incandescent body of gas is called a nebula. Nebulas are large clouds of dust and gas in outer space that emit light due to the energy generated by the stars or other processes happening within them.
Does the flame of gas stove emit light Explain.?
Yes it emit
What Gas is used in incandescent light bulbs?
Argon
What kind of gas goes in an incandescent light bulb?
An inert gas such as argon.
What is the white powder used in incandescent gas?
The white powder used in incandescent gas mantles is typically made of thorium dioxide. This powder is added to the fabric mantle to help it emit a bright white light when heated by the gas flame. However, due to health and environmental concerns, some manufacturers are moving towards using alternative materials.
Does the red light from glowing neon gas have only one frequency or a mixture of frequencies?
a mixture of frequencies.
What is the deference between incandescent and fluorescent lights?
An incandescent light uses electric current passing through a wire with a high resistance to current flow. That makes the wire very hot and it glows, producing the light. A fluorescent light uses electricity to charge a gas in a tube. The charged gas glows, producing the light. For the same amount of light, more electricity is needed in an incandescent light than in a fluorescent light, but developing and building fluorescent lights required more advanced technology than did incandescent lights.
How do bubbles emit light?
Bubbles can emit light when they are filled with a gas that is excited by an external energy source, such as sound waves or ultraviolet light. This excitation causes the gas molecules to release light photons, which creates the glowing effect seen in some bubbles.
What items are argon in?
Argon is commonly found in gas discharge tubes, incandescent light bulbs, and welding shielding gas.
