What does a white light bulb emit?
light and heat
What gives the color to the light in the bulb?
There is resistance in the light bulb which gives it its colour (the orange bulb) but in the white bulb (tbh don't know what is it called) it contains neon which gives it its white colour
Why light emitted by a bulb is yellowish in colour but from a fluroscent tube is white?
You are seeing the spectrum of the metal used in a light bulb. In a florescent tube you are seeing ultraviolet light being transformed into visible light by the internal phosphor coating.
Why does a light bulb light in a closed circuit?
A bulb does not light up if there is no voltage available across the bulb, or if the bulb is burned out.
Is light bulb a compound word?
No. The light bulb is two words, not a combination of light and bulb.

What is the difference between a black light bulb and white light bulb?
Light is available in a variety of wavelengths depending on the emitter. Black light is in the ultraviolet range. White light is a mixture of frequencies in the visible range.
What is the average battery life of a white light bulb?
That can vary A LOT, depending on the specific technology used (the type of light bulb), and the brand.
Where does white light comes from?
light as it originates from the sun or a bulb before it is broken into different frequencies
How can you change a green light to white light?
Change the color of the bulb. [mec3usa] merge the green light with red and blue light.
Which color of light cause bean plants to grow faster?
It will have the same effect as a flourescent light bulb. Its basically the same light. On a white flourescent light bulb, the inside has been frosted white to give off a white light. Without this coating, its the same as a black light. The uv rays are the same.

What can you use to cover a light bulb?
A electrical cord. If you have more questions go to Natalsiapatterson1@gmail.com
Is the light from an incandescent lamp monochromatic?
No, an incandescent bulb i.e. a bulb that emits light by the generation of heat, emits white light and is therefore not monochromatic. For a source to be monochromatic, the light emitted must be of a single wavelength.
What does a light bulb have to do with an electrical light source?
A light bulb is a source of electric light. In an incandescent light bulb, the glass bulb forms a protective shield around a glowing filament. The air inside the glass bulb is removed, or replaced with an inert gas. Electric current is passed through a thin metal filament (usually tungsten), which causes it to glow white hot, giving out light. The protective bulb stops the filament from burning up, as it has no Oxygen.
What is the brightest white light bulb?
There are bulbs that are designed to be bright.ÊThe wattage of a bulb does not tell how bright it is but is tells the amount of energy it uses.
