Why does Fluorescent bulb not light and end turns black?
In order to know why fluorescent bulbs turn black at the end, you need to understand how they work. Basically, when you turn on the lighht switch, the ballast sends a spark through the mercury-vapor-filled tube or bulb, depending on design. When it does this, it creates light by activating phosphors that coat the inside of the tube. Well each time the ballast fires, it creates emissions. These emissins materials then settle on the surface inside the glass. After awhile this material piles up. When it does this, the tube end turns completely black. Not only does the tube end turn black, but the accumulated materials pile up so high that it blocks the electrons that flow into the mercury. When this happens, you will notice the bulb or tube flicker heavily and then burn out.
How can I remove a tube light?
To remove a tube light, first turn off the power to the light fixture. Then, gently twist and pull the tube light out of the sockets on either end. Be careful not to break the tube light as you remove it. Dispose of the old tube light properly and insert a new one if needed.

Why tube light glowing white colour?
Mercury is present inside the tube light.When we give supply to the tube light the mercury vapours excites and it produces uv radiation which then strikes the fluorescent material and produces light. Therefore it is called fluorescent light.
What are the six main components of a fluorescent tube light?
The six main components of a fluorescent tube light are the glass tube, which contains the gas and phosphor coating; the electrodes, located at each end, that emit electrons; the mercury vapor, which ionizes to produce ultraviolet light; the phosphor coating, which converts UV light into visible light; the ballast, which regulates the current flowing to the lamp; and the end caps, which connect the tube to the electrical circuit. Together, these components enable the efficient production of light in fluorescent tubes.
Is the head end of a tube the closed end?
The head end of a tube can be the closed end. This depends on what the tube's purpose in the car is.
Why do optical fibers carry light long distances?
Imagine a plastic tube with an inside surface that is a high quality mirror. If you were to direct light into one end of this tube the light would bounce of the mirrored walls of this tube indefinitely, (regardless if the tube curves or twists) and you will see the light at the other end. if you were to send the light in an organised code it can then be used in communication. In scenes this is how fibber optics works. fibre optics are made with super fine quality glass drawn out to about the thickness of a human hair with plastic coatings around them to make the inside of the grass reflective and protect it.
How does light works?
Light from a electric bulb is generated when the negative & positive prongs inside generate a spark upon touching creating light.
Why black color absorb all the color but not absorb black?
Because black is not a color ... it's where there is no color at all. At night, when the light in your room is on, everything you see has a color, and when you turn the light off, everything is black ... no color. When you see the colors spread out ... in a rainbow, or a picture of the visible spectrum in a book ... one end is red, the other end is blue, and then there's black on both ends. Black is not a color that magically appears at two different places in the rainbow. It's the way the region appears when there is no more color.
How does a fluorescent light work?
Mercury, Phosphorus, and Argon are arranged inside of the glass bulb in such a way that it reacts in a specific way. The mercury vapour is heated to form a gas and then high voltage passed through the tube from one end to the other. The gas emits ultra violet light. The inside of the tube is coated with a phosphor coating which lights up (fluoresces) when UV hits it, causing it to emit visible light. Tweaking the chemical composition of the phosphor coating, can provide different shades and colours of light. No coating, gives UV (black) light. There are two heating electrodes at each end of the tube. On switch on, current is applied through both heaters via a ballast coil and the circuit completed through a bimetal switch (starter). The heaters heat up, then the switch opens, causing a high voltage surge from the ballast. The high voltage causes the mercury vapour to conduct electricity through the tube, at low resistance, causing it to emit UV light. The current is limited by the ballast coil. If the vapour fails to strike, then the bimetal switch cools and then closes again, starting again, until the tube 'strikes'. This is what causes the lamp to flicker before coming on. Once the tube has lit, the low resistance path through the tube effectively takes the starter and heater out of circuit. The heater ends act just as electrodes into the gas filled tube.
Can artificial black light harm you?
Black light can pose a hazard to the eyes and the skin. Black light is, after all, light at the violet end of the spectrum and it has ultraviolet components. UV light is higher energy light and can be damaging. Get the straight dope by reading the Wikipedia article. The link is below.
