A neon light is more similar to an incandescent light or a fluorescent light explain how you know?
A neon light is much more similar to a fluorescent light. I know because I have a Ph.D. in physical chemistry, but I suspect you mean "justify your answer," so here goes. In a gas-discharge light (a neon light), a gas is ionized by an electric potential. Free electrons are then accelerated through the ionized gas. This causes the ions to transition into an excited electronic state. When the ion decays back to the ground state, energy of characteristic frequencies is emitted; the dominant frequencies depend on the gas, the voltage, and the pressure. This is why neon lights are orange-red: the dominant characteristic visible frequencies for neon gas are in the orange-red portion of the spectrum. (If you see a "neon" light that isn't orange-red, it's probably not really using neon gas.) A fluorescent light is exactly the same, except that the inside of the tube is coated with a fluorescent material. It absorbs the (high frequency) energy emitted by the gas discharge itself, and emits energy at a lower frequency (characteristic of the specific material). The gas in fluorescent lights is usually low-pressure mercury vapor, whose dominant emisison frequencies are in the ultraviolet. This is absorbed by the phosphor in the tube and re-emitted as a lower frequency (in the visible spectrum). Most fluorescent lights have a mixture of phosphors so that the emitted light appears "white" because it's actually a mix of different colors that kind of "average out" to white (this is like how the red, green, and blue phosphors in a CRT "blend" to appear white). To confuse matters even further, a lot of modern "neon" lights are actually just fluorescent lights with a colored dye or sleeve applied to the tube (if the tube, when off, appears white, colored, or "cloudy", it's probably a fluorescent light instead; if it's clear and looks empty, then it's pure gas-discharge). This allows for the production of "neon" lights of any color desired and also allows different sections of the tube to have different colors. An incandescent light glows because it's hot ("black body" radiation or "cavity" radiation). There's no characteristic frequency, though there is an emissions maximum which varies depending on temperature. If it's relatively cool ("red hot" is relatively cool as used here), it will appear a dull red; as it gets hotter it turns bright red, then orange, then yellow, then white, and ultimately starts to appear to have a bluish tinge as the emissions maximum shifts to shorter and shorter wavelengths.
Does Texas produce more fuel from trash than any other state in the US.?
Yes, Texas produces more fuel from trash than any other US state.
A change of state in which energy is removed from a substance is called an?
A change of state where energy is removed from a substance is called an exothermic reaction. This chemical reaction releases energy in the form of light or heat.
What does the word natural light mean?
It's something that emits its own light, and not just reflects it. An example of a natural source would be a star whereas the moon is not, even though it glows. The moon's light is due to reflection. Fast moving and highly charged ionic particle also can emit their own light, or something that has electrons which go from a higher energy state to a lower energy state, even though that light isn't always visible.
State what features the moss and fern have in common?
They both need moisture and both produce spores to reproduce.
Which state help produce light in fluorescent light bulbs?
Which state helps produce light in fluorescent lightbulbs?
Which state helps produce light in fluorescent light bulbs?
Mercury vapor gas in fluorescent light bulbs helps to produce ultraviolet light when an electric current passes through it. The ultraviolet light then causes the phosphor coating inside the bulb to glow and produce visible light.
Is fluorescent light a plasma?
No, fluorescent light is not a plasma. Fluorescent lights work by using electricity to excite mercury vapor and produce ultraviolet light, which then interacts with a phosphor coating to create visible light. Plasma is a state of matter where atoms are stripped of their electrons, leading to a highly energized gas that can emit light.
Which state of matter forms when a fluorescent light bulb is turned on?
A fluorescent light bulb produces light by exciting the gas inside it, usually mercury vapor or neon. The excited gas atoms emit ultraviolet light, which stimulates a phosphor coating on the inside of the bulb to produce visible light. So, when a fluorescent light bulb is turned on, it emits light through a process involving excited gas and phosphor.
What state of matter forms when fluorescent light bulb is turned on?
When a fluorescent light bulb is turned on, it produces light by generating plasma. Plasma is the fourth state of matter, distinct from solid, liquid, and gas, characterized by its ionized particles that conduct electricity.
When a fluorescent light bulb glows what state of matter is it?
it is plasma , gas and liquid
Does fluorescent light have plasma?
No, fluorescent lights use electricity to excite mercury vapor inside a glass tube, causing it to emit ultraviolet light. This ultraviolet light then interacts with the phosphor coating on the inside of the tube, producing visible light. Plasma is a state of matter where atoms are ionized, unlike the process in fluorescent lights.
When a common fluorescent lamp is on the mercury vapor inside is actually in a which state?
When a common fluorescent lamp is on, the mercury vapor inside is in an excited state. When an electric current passes through the mercury vapor, it excites the mercury atoms, causing them to release ultraviolet light. This ultraviolet light then interacts with the phosphor coating on the inside of the lamp, producing visible light.
How is a fluorescent light made?
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.
What kind of light does fluorescent light produce?
Main one is light energy. Also some heat is produced
What is the need for fluorescent material?
Fluorescent materials are needed for a variety of applications such as lighting, bioimaging, and security features. These materials are able to absorb light at one wavelength and emit it at a different, longer wavelength, making them useful for creating efficient light sources, visualizing biological processes, and preventing counterfeiting.
What are CFL and LED lights?
A compact fluorescent light (CFL) is a fluorescent light that is manufactured in the approximate size and shape of a standard incandescent lamp. It's got an electronic ballast (unlike the standard fluorescent lamp tube which uses a heavy wire wound ballast), and it screws into a socket and performs on the standard line voltage like that aforementioned incandescent lamp. The light emitting diode (LED) is a solid state device that converts electricity into light without heating a filament like the incandescent lamp, or ionizing a gas like the fluorescent light does.
