Photons travel outward from a light bulb in all directions


The good thing about light bulb is that it gives us light to see where ever we go or travel.


In 1960, Theodore Maiman invented the laser while working at Hughes Research Laboratory. The laser emitted photons that struck other photons and generated more photons. The set up allowed for a systematic emission of photons, and after gaining ample intensity they formed a consistent beam of light.


Inside the trunk or hatch, remove the nuts(often 4)that are on the inside near your tail light. The whole tail light assembly can be pulled outward to change the bulb. The bulb assembly twists off. Replace bulb. Assemble in reverse order.


Current passing through a special wire like tungsten heat up the wire and create light by emitting photons


Exactly the same way it travels from the sun ... in the form of electromagnetic radiation, which is really the only way for light to travel, because that's what light IS.


Electricity doesnt have a speed, it is instantaneous.


This is the case in any bulb that heats a filament. The current flowing through the filament generates heat which radiates photons and produces the light you see.


It could not travel at the speed of light. But hypothetically, it would glow.


A Light bulb lights in a complete circuit because then the electricity from the battery can travel round the wire that has no breaks. BUT the switch has to be close. Z


coherent light is a light in which the electromagnetic waves maintain a fixed and predictable phase relationship with each other over a period of time. Additional Information (S) Incoherent light contains may different wavelengths and amplitudes of light, such as light from a light bulb. Coherent light is a beam of light where all of the photons are the same frequency and interval. If you think of photons like people, a laser is a coherent group of photons like a column of soldiers marching in a long parade, whereas incoherent light is more like everyone exiting from the movie theater.


electircal or photo electrical energy. Photons are shot across from panel to another panel this sparking back and forth creates the light you see.Answer: Electricity is the energy input into a light bulb. It either heats afilamanet to produce heat and light, r excites the gas contained in the bulb (in flluorescent tube) to emit visible light directly or emit UV light which interacts with a phosphor coating in the tubes to emit light.


it varys from light bulb to light bulb.


An incandescent bulb differs from a fluorescent based on how it produces light. "Incandescent" means producing light through heat, this is essentially how an incandescent bulb lights. As current travels to the tungsten filament, the filament heats and lights up as the tungsten filament begins to deteriorate and eventually fail. Fluorescent bulbs produce light when current excites gasses inside the glass envelope. As the gasses get excited they emit photons. Interestingly, the light produced by a fluorescent bulb does not fall along the visible spectrum until it passes through the white, phosphor coating on the inside of the bulb. And there you have it.


Light bulb provide electrical light.


No. The light bulb is two words, not a combination of light and bulb.


Given the wavelength of the photons from above, 3000 nm you just calculate how many joules each photon has and divide that into 100 joules per second.


If you increase the current in an ordinary incandescent light bulb, the light bulb will get brighter.


A fluorescent bulb uses a completely different method to produce light. There are electrodes at both ends of a fluorescent tube, and a gas containing argon and mercury vapor is inside the tube. A stream of electrons flows through the gas from one electrode to the other (in a manner similar to the stream of electrons in a cathode ray tube). These electrons bump into the mercury atoms and excite them. As the mercury atoms move from the excited state back to the unexcited state, they give off ultraviolet photons. These photons hit the phosphor coating the inside of the fluorescent tube, and this phosphor creates visible light. It sounds complicated, so lets go through it again in slow motion:There is a stream of electrons flowing between the electrodes at both ends of the fluorescent bulb.The electrons interact with mercury vapor atoms floating inside the bulb.The mercury atoms become excited, and when they return to an unexcited state they release photons of light in the ultraviolet region of the spectrum.These ultraviolet photons collide with the phosphor coating the inside of the bulb, and the phosphor creates visible light.The phosphor fluoresces to produce light.A fluorescent bulb produces less heat, so it is much more efficient. A fluorescent bulb can produce between 50 and 100 lumens per watt. This makes fluorescent bulbs four to six times more efficient than incandescent bulbs. That's why you can buy a 15-watt fluorescent bulb that produces the same amount of light as a 60-watt incandescent bulb.


electromagnetic waves generally don't require a medium to travel. the most commonly visible example is "light" which may be either sun's light, light from a bulb or any other source. they travel as transverse waves.


The plural of light bulb is light bulbs.

A light bulb that uses a filament is also known as an incandescent light bulb.


Two possibilities: the light bulb is broken or there is no electricity getting to the light bulb


No. Laser light is coherent. Light bulb light is not.
