What is a 6500K fluorescent bulb?

It's a bulb with more blue light in it, to better match the light that natural sunlight emits.


Is lightning a light source or reflector?

Lightning is not a traditional light source like the sun or a light bulb, as it does not produce light through a thermal or chemical process. Instead, lightning is an electrical discharge that generates light as a result of the rapid heating and ionization of air molecules along its path. Therefore, lightning can be considered a light source in the sense that it emits light, rather than a reflector that simply bounces light off its surface.


What is the difference between incandescent and fluorescent light bulbs?

Incandescent lightbulbs have an electrical circuit that passes through a tungsten wire. As the electricity flows, the tungsten is heated up to a point where it emits light waves. Gases (xenon, I think) help sustain the wire until it breaks. This is when the light stops and needs to be replaced. (the tungsten also emits heat when lit) Incandescent lights have the full spectrum of colors. Fluorescent bulbs are filled with a gas and a bit of mercury. Electricity gives the ions in the gas energy, which is released in the form of light. This method sustains the bulb far longer than an incandescent lightbulb. Fluorescents release much less heat, making them more energy efficient. However, the spectrum of the fluorescent bulb is missing a few colors of the spectrum, which makes the spectrum look cool and incredibly weird.A fluorescent lamp or fluorescent tube is a gas-discharge lamp that uses electricity to excite mercury vapor. The excited mercury atoms produce short-wave ultraviolet light that then causes a phosphor coating on the inside of the bulb to fluoresce (glow), producing visible light.


What is the difference between a light source and a reflector provide examples for each?

A light source generates and emits its own light. A reflector reflects light (i.e. light bounces off of it) from another source. Examples of light sources: The sun, the stars, a lightbulb, a flame, a red-hot piece of metal. Examples of reflectors: The moon, the planets, the ground lit by the sun.


What does emitting mean in science?

emit means for something to "give off"e.g.uranium emits radiationa cup of hot water emits heatect.

Why is it marked 6500k on fluorescent lamps?

If a fluorescent lamp is labeled 6500 oK that is the color temperature of the light it emits. <><><> The number 6500 refers to the temperature (measured in degrees Kelvin) at which a specific theoretical material (referred to as "black body") will glow the color of sunlight at noon.


What wavelengths does a high temperature source radiate?

A high temperature source such as the Sun emits radiation across a wide range of wavelengths, from ultraviolet to visible light to infrared. The peak wavelength of radiation emitted by a high temperature source is determined by its temperature according to Wien's displacement law.


What is an extended source of light?

An extended source of light refers to a light source that is not a point source, meaning it has a finite size and emits light over an area rather than from a single point. Examples include fluorescent tubes, incandescent bulbs, and the sun.


How can plants benefit from fluorescent light?

Plants can benefit from fluorescent light because it provides a source of artificial light that can help them with photosynthesis, growth, and overall health. Fluorescent light emits the right spectrum of light that plants need for their growth and development, making it an effective alternative to natural sunlight for indoor plants or in areas with limited sunlight.


What are fluorescent materials illuminated with?

Fluorescent materials are typically illuminated with ultraviolet (UV) light. When UV light is absorbed by the fluorescent material, it re-emits visible light at a longer wavelength, creating the characteristic fluorescence.


Do incandescent and fluorescent bulbs produce the same amount of heat?

No, incandescent bulbs produce more heat than fluorescent bulbs. Incandescent bulbs generate light by heating a filament, which also emits heat. Fluorescent bulbs produce less heat because they use electricity to excite gas inside the bulb, which then emits light.


What material lines the tubes of fluorescent lights and glows to UV Light?

Phosphor coating lines the inside of fluorescent light tubes. When the gas inside the tube is excited by electrical current, it emits ultraviolet (UV) light. The phosphor coating then absorbs the UV light and re-emits it as visible light, creating the glow from the fluorescent light.


How does the frequency of radiant energy relate to the absolute temperature of the radiating source?

A low temp source emits low-frequency, long wavelength waves. A medium temp source emits medium frequency, medium wavelength waves. A high temp source emits high frequency, short wavelength waves.


What are the Energy pathway for fluorescent source?

Fluorescent bulbs produce light by passing an electric current through a tube filled with mercury vapor and a phosphor coating. The electric current excites the mercury vapor, producing ultraviolet light. The phosphor coating then absorbs the ultraviolet light and re-emits it as visible light.


How does the fluorescent lighting work?

ionized Mercury vapor emits UV light.phosphor coating on inside of tube absorbs UV light and emits visible light.visible leaves tube.


A sound source of high frequency emits a high?

How does a fluorescent bulb convert ultraviolet light into visible light?

A fluorescent bulb contains a gas that emits ultraviolet light when electricity passes through it. The inner coating of the bulb is made of phosphor, which absorbs the ultraviolet light and re-emits it as visible light. This process is known as fluorescence.
