What are light sources and non light sources?
The sources that can give out their own light are "Light Sources" and the same opposite the sources which can not give out their own light are know as Non Light Sources .
What powered the light bulb back in the 19 century?
Electricity powered the light bulb in the 19th century. Thomas Edison is considered to be the inventor of the modern light bulb.
How do you produce two coherent sources of light?
two coherent light sources are produced by splitting a single light source
What are coherent sources and conditions for it?
Coherent sources are sources of light with a constant phase difference. The conditions for this are that there is a constant phase difference and that the light is of the same wavelength.
How does static electricity make light when it is discharged?
it is solar powered
What are two sources of visible light waves?
A primary light source is one that actually produces light, such as a light bulb or the sun. A secondary light source in one that ONLY reflects the light produced by a primary light source. It doesn't produce light itself, such as a mirror or the moon.
What are light sources and non light sources?
The sources that can give out their own light are "Light Sources" and the same opposite the sources which can not give out their own light are know as Non Light Sources .
What is the conclusion for a battery powered light bulb?

What are alternative sources for battery powered tooth brushes?
Siemen
What is the fastest human powered vehicle?

How are bike lights powered on a manual bike?
Bike lights can be powered by multiple forms of power. The most common type of light is battery powered and that is easiest to install. Another type of bike light is solar powered during the day and shows light at night.
What are two sources of EMI?
High powered electrical wiring and florescent lights.
How many Light sources are available for optical fiber?
There are 142 light sources. The types of light forms are Natural which are Celestial and atmospheric light, terrestrial, and nuclear or high energy related. Other categories are direct chemical, electric powered, electron stimulated, incandescent lamps, electroluminescent lamps, gas discharged lamps, high intensity discharge, laser, combustion, nuclear, and others.
What are the types of sources of light?
That is a bigger question than you might imagine. First you have to consider what wavelength of light you might be looking for. Electromagnetic radiation (light) can be anything from radio waves, through microwaves, infra red, visible light, ultra violet and x rays to gamma rays and beyond. If we are talking about practical sources of visible light that are man-made then we have several devices in common use today including incandescent light bulbs, flourescent light bulbs, light emitting diodes (LEDs), lasers, electric arc lamps and gas discharge lamps. There are patents existing for many other types but they are not in common use today. All the types listed above are powered by electricity. Other practical sources of light that do not need electicity are powered fundamentally by chemical reactions. These include candles, oil lamps, fireworks (flares) and glow-sticks.
What powered the light bulb back in the 19 century?
