When did Theodore Maiman invent the first light bulb?
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.
What causes filament in a light bulb to glow?
Current passing through a special wire like tungsten heat up the wire and create light by emitting photons
If the light bulb from number 10 radiates 100 watts times 100 joules per second of photons. How many photons per second are radiated?
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.
Where should the bulb be placed in headlights if the beam of light have to travel long distance?
center of curvature C
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.
How do photons travel outward from a light bulb?
Photons travel outward from a light bulb in all directions.
How do photons travel from a light bulb?
Photons travel outward from a light bulb in all directions.

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

How do you replace the brake light on a Ford Mustang?
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.
Why are electric light bulbs hot to the touch?
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.
IF a bulb travels at the speed of light and is turned on will it glow?
It could not travel at the speed of light. But hypothetically, it would glow.
How a light bulb works in a complete circuit?
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
If the light bulb from number 10 radiates 100 watts times 100 joules per second of photons. How many photons per second are radiated?
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.
What is the difference between Coherent and incoherent light?
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.
What does Mercury do in a CFL?
Without the mercury in a CFL you wouldn't have light. The ballast in a CFL supplies initial current which excites the mercury which releases photons, or light. The mercury does not produce visible light, this happens only once the light passes through the phosphor coating on the inside of the bulb.
