Incandescent bulbs work by conducting an electric current along a filament made of a long, thin piece of tungsten metal. The filament must be heated to temperatures of about 2,300 degrees Celsius to glow and emit a yellow-hot light. CFL bulbs, on the other hand, are made of glass tubes filled with gas and a small amount of Mercury .White Light is emitted when mercury molecules in a CFL bulb become excited by electricity running between two electrodes at its base. The mercury emits an invisible ultraviolet light that becomes visible when it hits the white coating inside the CLF bulb.
Bulbs produce yellow light because they have a filament that heats up and emits light at lower temperatures, typically around 2700K. Tube lights, on the other hand, use electricity to excite gases inside the tube, producing a bright white light closer to natural daylight at around 5000-6500K.

What gives the color to the light in the bulb?
The color of the light produced by a bulb is determined by the type of filament or gas inside. For example, tungsten filaments produce a warm yellow light, while fluorescent bulbs use phosphors to convert UV light into visible light. LED bulbs use a semiconductor to emit light, and the color can be adjusted by using different materials.
What does a white light bulb emit?
A white light bulb emits a combination of all visible wavelengths of light, which is perceived by our eyes as white light. This combination includes red, blue, and green wavelengths of light.
What is a word for the threadlike wire that gives off light in an electric light bulb?
Filament.
What forms of energy are given off by a light bulb?
A light bulb gives off mainly light energy as well as heat energy. When electricity flows through the filament in the bulb, it gets hot and emits light.
What 2 forms of energy does a light bulb give out?
A light bulb gives out light energy and heat energy as forms of energy. The light energy is emitted as visible light, while the heat energy is generated as a byproduct of the bulb's operation.
What gives the color to the light in the bulb?

For example, tungsten filaments produce a warm yellow light, while fluorescent bulbs use phosphors to convert UV light into visible light. LED bulbs use a semiconductor to emit light, and the color can be adjusted by using different materials.
What is the wire that gives off light in a light bulb?
In an incandescent light bulb the wire that gives off the light is called the Filament.
What is the Function of light bulb in an electric circuit?
The function of a light bulb in an electric circuit is that it turns electrical energy into light.
What is the use of a light bulb?
How about, it gives off light.
Why is a light bulb important?
it gives us light
What does a yellow light that looks like a light bulb with an exclamation in the middle means on a vw touareg?
What does a yellow light that looks like a light bulb with an exclamation in the middle means on a vw touareg?
What is the difference between led light and a normal light bulb?
a normal light bulb gives off more light
There is a yellow bulb shape with this sighn on the dashboard what is it?
The yellow light bulb indicates that there is a blown bulb ( taillight, turn signal, etc.) somewhere on the vehicle.
What part of a light bulb gives off electricity?
The filament or LED component inside a light bulb is what gives off light when electricity flows through it. The electrical energy is converted into light energy by the filament or LED.
Is a light bulb an example og electromagnetic energy?
A light bulb is not an example of electromagnetic energy, but the light which the bulb gives off is an example of electromagnetic energy.
What does a white light bulb emit?
A white light bulb emits a combination of all visible wavelengths of light, which is perceived by our eyes as white light. This combination includes red, blue, and green wavelengths of light.
In the scene with the light bulb what colour was the number 7?
Yellow
