It doesn't 'USE' any; that is, you don't have to provide any electromagnetic waves in order for a light bulb to do its job.
In the course of doing its job, the light bulb PRODUCES light and heat waves.
A fluorescent light also produces radio waves.

Can you use carrots and onions to power light bulbs?
you can use an oingion but not a carrot
Why do ordinary light bulbs take more electrical energy than efficient bulbs?
The filament on normal light bulbs require a higher current of electricity to light up, and are more resistant to electricity as well. This causes it to use more electricity and generate more heat.
Why can light bulbs be called heat bulbs?
Heat bulbs would be a more appropriate name because incandescent bulbs transform 90% of electricity received into heat and 10% into light. New Compact Fluorescent light bulbs use only 20% to 30% of the energy needed to power a standard bulb for the same wattage.
Clear vs frosted light bulbs?
Those wanting softer, diffused light use frosted light bulbs. Clear bulbs give light that is brighter and suitable for everyday applications.
What light bulbs provide the most natural light?
Any natural light bulbs that use incandescent lighting will work well, and give off a rounder light than the "sterile white" lighting of normal bulbs.

When do you use a circuit?
Anytime you ask electricity to do anything for you. Turn on light bulbs, start a car, run ann engine, watch TV. Anytime electrical power is used.
How is the new light bulbs energy renewed?
The energy put into the bulb is converted to heat and light. Low-energy bulbs just use less electrical energy to keep them bright.
If some of your ceiling light bulbs are out eg 3 out of 6 does this waste electricity?
No, dude bulbs do not use any power.
Do light bulbs make their own light?
No, they use the house's power to convert electricity into a lot of heat and a little light.
How do you prove that the size of a light bulb does not matter for energy use?
What matters is the electrical power it uses in watts and the amount of light in lumens. The size of the light does not matter, whch can be proved by trying bulbs of different sizes with the same watt and lumen rating.
Why do energy saving light bulbs save money?
Because they use less power
How do you transform electrical energy to light energy?
You use a light bulb.Such light bulbs use different types of technology; for example, the old-fashioned (and quite inefficient) incandescent bulb heats a wire, which acts as an electrical resistance, to the point where it glows.
Why do ordinary light bulbs take more electrical energy than efficient bulbs?
The filament on normal light bulbs require a higher current of electricity to light up, and are more resistant to electricity as well. This causes it to use more electricity and generate more heat.
Is a light bulb an example of light energy or of electrical energy?
A light bulb converts energy from one form to another: from electrical energy to thermal energy in the form of light and heat. Most light bulbs which have an incandescent filament convert electricity into some light energy plus a lot more heat energy, whilst the type of light bulbs which use fluorescent tubes create much less heat and thus require much less electrical energy to run. Typically, to produce the same amount of light energy, compact fluorescent light bulbs require only 20% of the electrical power drawn by incandescents.
How do you know if the bulbs r bad or if it is an electrical problem or fuse in a 1998 ford epedition xlt?
Use a test light to analyze the circuit. Use a test light to analyze the circuit.
