How does light produce?

Answer 1

1) from the sun's rays. 2) from the filament in any household lightbulb.

Answer 2

There are three ways a luminous object (anything that can give off its own light)

can produce light. Light produced by heat, or incandescent light, is like a light bulb.

When you touch a lit light bulb after it has been on for a while, it's hot to the touch.

Fluorescent light uses a lot less electricity than incandescent light bulbs. Electrons

are used to bombard gas molecules at a low pressure in tubes. Examples include the

tube lighting in schools and corporate buildings. The last mean of producing light is

neon light. And, not surprisingly, electrons pass through neon gas to make light

most of the time. Other gases used for the neon lights we see throughout big cities

are Mercury, sodium,and many more.

==============================================================

The two answers above explain all of the ways that visible light can be produced.

There are no other ways.

Except for electrostatic discharge, such as is seen in lightning and zapping your

Answer 3

Slightly confused by your question. Are you refering to the production of visible light? Or are you referring to production of energy using light?

Production of energy from light:
This is referred to photosynthesis, this occurs in autotrophe organisms. It goes through a process that uses photons (packets of light) and carbon dioxide to produce chemical energy inside the cells and releases a byproduct of oxygen.


Production of visible light:
The visible spectrum for the human eye are wavelengths between 380 to 750nm. So a energy source must emit within that spectrum.

Example: LED, a light emitting diode is produced from a current of electricity running through a diode which creates resistance and emits a light within the visible spectrum.

Answer 4

Light can be produced from heat and can use electricity to ionized the gas and produce light.
