Aug 27, Craig Mar 12, Don't be rude. I'm actually going to use this website for my science fair project. Mar 25, Hi, sarah! We're glad to hear you'll be using Wonderopolis for your science fair!
Mar 13, We're sorry to hear that, Craig. RIRI Sep 25, RiRi Feb 20, Feb 20, Emmy Mar 21, Mar 21, We're glad it lights you up, Emmy! Oct 1, Colten Oct 14, This was really helpful! Why do people shake the light bulb to see if it works or not. Oct 18, Oct 7, We're glad you enjoy Wonderopolis, jovona!
We hope you'll visit again soon! Aug 22, That's very true, noelle! Jayda loves wonderopolis Mar 5, I thought that Nikola Tesla invented the lightbulb. He for a short period of time worked with Thomas Edison. My science teacher said that Nikola Tesla invented the lightbulb, and that Thomas sort of stole his idea! Is this true?

Why does the lightbulb turn on so fast? D Aug 26, Emily smith Aug 26, Harlee w Aug 26, Brody H Aug 26, How many tries did it take Edison, and Swan to create the light bulb? Jeshaiah B. I liked this story. How do you come up with all of this information about these things. Breven Aug 26, Do you just throw it away or do you do anything specific to it before you throw it out?
Genevieve V Aug 26, Why did the light bulb have to be so complacated! Now all you have to do is flip a swich and the light or fan comes on! Bianca Aug 26, Mckalynne Aug 26, How fast does a light bulb turn on?
How fast is the speed of light?

One of those people was British physicist Joseph Wilson Swan, who actually received the first patent for a complete incandescent light bulb with a carbon filament in Edison and Swan merged their companies and together they were the first to design a bulb that was commercially viable.
An incandescent bulb typically consists of a glass enclosure containing a tungsten filament. An electric current passes through the filament, heating it to a temperature that produces light.
The enclosing glass enclosure contains either a vacuum or an inert gas to preserve and protect the filament from evaporating. Incandescent bulbs require no external regulating equipment, have a very low manufacturing cost, and work well on either alternating current or direct current. They are also compatible with control devices such as dimmers, timers, and photo sensors, and can be used both indoors and outdoors. As a result, the incandescent lamp is widely used both in household and commercial lighting, for portable lighting such as table lamps, car headlamps, and flashlights, and for decorative and advertising lighting.
Many incandescent bulbs are scheduled to be phased out of production by Electrons of different energy levels occupy different orbitals. Generally speaking, electrons with greater energy move in orbitals farther away from the nucleus. When an atom gains or loses energy, the change is expressed by the movement of electrons. When something passes energy on to an atom, an electron may be temporarily boosted to a higher orbital farther away from the nucleus. The electron only holds this position for a tiny fraction of a second; almost immediately, it is drawn back toward the nucleus, to its original orbital.
As it returns to its original orbital, the electron releases the extra energy in the form of a photon, in some cases a light photon. The wavelength of the emitted light which determines its color depends on how much energy is released, which depends on the particular position of the electron.
Consequently, different sorts of atoms will release different sorts of light photons. In other words, the color of the light is determined by what kind of atom is excited.
This is the basic mechanism at work in nearly all light sources. The main difference between these sources is the process of exciting the atoms. Sign up for our Newsletter!
