What is the difference between red hot and white hot?

When some objects get hot enough, they glow, given off a faint red light . If they get even hotter, the glow turns into white light. The objects are said to be white light


What is the difference between blacks and whites?

Black is a dark color and is the color of this typing and white is a light color it's the color of some of this page! If you compare this to a human there is no difference, we are all the same and should not be looked at differently. There is no reason for black people to wear lighting cream to make them lighter, and there is no reason for white people to get a tan for darkness either. We are special in tones and who we are.


What is the difference between white fluorescent lights and yellow ones?

Florescent bulbs are environmental-friendly. Yellow bulbs use more electricity, but their lighting is generally better. Most florescent bulbs take at least a full minute to reach their full lighting, therefore conserving energy when you don't need full lighting. Florescent bulbs are environmental-friendly.

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.

What is the difference between daylight fluorescent and warm white fluorescent?

The light from a "Daylight" type looks brighter to the eye than "Warm White". The "Daylight" type is supposed to make colors of things (clothes, furniture, etc.) look more natural, as if they were outside in daylight. The "Warm White" type is supposed to be more restful for our eyes when we have to live or work for long periods using artificial lighting. It also is supposed to look more like the light from conventional incandescent filament lamps.


What are the different colors of fluorescent lighting available?

What are the different fluorescent color temperatures available for lighting options?

Fluorescent lighting options are available in different color temperatures, including warm white (2700-3000K), cool white (3500-4100K), and daylight (5000-6500K).


What is the difference in the wavelength of light between broad daylight and night?

Broad daylight has shorter wavelengths of light, which appear as white light, while at night, longer wavelengths of light, such as red and orange, are more prevalent.


What are the different gases introduced into fluorescent lamps that give them their specific colors?

I think that you may be confusing fluorescent tubes with neon tubes. Fluorescent tubes use a phosphor coating on the inside of the lamp which is in a limited spectrum. Some tubes are cool white, warm white, and daylight. There is also a gro lux which is on the warm end of the spectrum used for growing indoor plants.

How can I adjust the white balance on my camera to properly capture the colors under fluorescent light?

To adjust the white balance on your camera for fluorescent light, go to the white balance settings and select the fluorescent light option. This will help your camera capture the colors accurately under fluorescent lighting conditions.
