What is a source of light that produces light through a chemical reaction?

A source of light that produces light through a chemical reaction is a chemiluminescent light. Chemiluminescence occurs when certain chemicals undergo a reaction that results in the emission of light energy. This type of light production is commonly seen in glow sticks, where mixing two different chemicals creates a glowing effect.

Which source of light emits light by heating a filament?

An incandescent light bulb emits light by heating a filament inside the bulb until it glows white-hot and produces light.

Name a natural source of light that is found in the sky during the day.

The Sun is a natural source of light that is found in the sky during the day.

Which source of light produces light by passing an electric current through a gas?

The source of light that produces light by passing an electric current through a gas is a fluorescent light.

Identify a source of light that emits light by passing an electric current through a small space.

An example of a source of light that emits light by passing an electric current through a small space is a fluorescent light bulb.

Name a source of light that emits light when an object becomes very hot.

Incandescent light bulbs emit light when the filament inside becomes very hot due to the flow of electricity.

What is a source of light that produces light through the emission of photons from atoms or molecules?

A source of light that produces light through the emission of photons from atoms or molecules is known as a luminescent source. This type of light source includes technologies such as fluorescent lamps, light-emitting diodes (LEDs), and lasers, where the atoms or molecules are stimulated to emit light by an external energy source.

Which source of light emits light through the excitation of phosphors by ultraviolet rays?

Fluorescent lamps are a source of light that emits light through the excitation of phosphors by ultraviolet rays. When electricity passes through the lamp, it produces ultraviolet light which then excites the phosphor coating on the inside of the lamp, causing it to emit visible light.

Identify a source of light that produces light through the combustion of a wick soaked in flammable liquid.

A source of light that produces light through the combustion of a wick soaked in flammable liquid is a traditional oil lamp or commonly known as a kerosene lamp.

Name a source of light that emits light due to the passage of an electric current through a vacuum.

An incandescent light bulb is a source of light that emits light due to the passage of an electric current through a vacuum or inert gas within the bulb.
