A tube bulb works by passing an electric current through a gas or vapor inside the tube, which causes the gas particles to become excited and emit light. The tube is coated with a phosphor material that absorbs this light and re-emits it as visible light. The specific type of gas, voltage, and phosphor coating determine the color and intensity of the light produced.

How does a fluid expansion thermometer work?
A fluid expansion thermometer consists of a bulb filled with a liquid, typically mercury or alcohol, connected to a capillary tube. As the temperature increases, the liquid in the bulb expands and rises up the capillary tube. The temperature is read by measuring the height of the liquid in the tube, which corresponds to the temperature scale on the thermometer.
Why does a tube light cast a dim shadow than a bulb?
A tube light casts a dim shadow compared to a bulb because the light emitted by a fluorescent tube is more diffused and spread out, resulting in softer edges and less contrast in the shadow. Conversely, a bulb emits light in all directions, including towards the shadow, creating a sharper and darker outline.
What a thermoscope is made of?
A thermoscope is typically made of a glass tube filled with a liquid such as alcohol or mercury. It has a bulb at one end and a narrow tube extending from the bulb. The liquid expands and rises in the tube when the temperature increases.
what is the long thin light bulb called?
The long thin light bulb is called a fluorescent tube or a fluorescent light bulb. It is commonly used in commercial buildings, offices, and schools for general lighting purposes.
Why is the walls of long tube above the thermometer bulb are made thick?
The walls of the long tube above the thermometer bulb are made thick to provide insulation and minimize heat transfer from the environment, ensuring that the temperature measurement at the bulb is accurate and not influenced by external temperature changes. Thicker walls also help protect the thermometer from physical damage.
What is a dropper and what are its uses?
A dropper simply is a small tube with a air-filled bulb at the top. You squeeze the bulb at the top and whatever substance the tube is submerged in, it will be pulled up into the tube. After that, you lightly squeeze the bulb again to release the substance in the tube out.
What is a long bulb?
A Tube-light !
How does the fluorescent light bulb work?
ionized mercury vapor emits UV light.phosphor coating on inside of tube absorbs UV light and emits visible light.visible leaves tube.
How does a fluid expansion thermometer work?

When should you replace a fluorescent light bulb?
when the tube ends blacken after failure of the tube heaters
Does this TV have a bulb that will ever need replaced?
There are several bulbs in this television not to be confused with a picture tube,it is possible that a bulb may need to be replaced. The tv does indeed have a bulb inside of it. You will not have to replace it unless something goes wrong and its broken it may need to be replaced to work again.
What is baster?
A baster is a person who, or a tool which, bastes something.
How does a bulb thermometer work?
A bulb thermometer contains a liquid that expands when heated and contracts when cooled. This causes the liquid to rise and fall within the tube, indicating the temperature. The temperature is then read off a scale on the tube to determine the measurement.
Does the middle bulb on the tail light work?
If there is a bulb, it should work.
How does a dropper work?
If you squeeze the bulb to expel most of the air, then release it with the tip under water, the pressure in the bulb drops and external air pressure on the surface of the liquid in its container forces the liquid into the dropper. When you squeeze the bulb again, you increase the pressure and force the liquid out.
Which bulb is fuse 25w or 100w which is connected in parallel?
Florescent tube
How much is a fluorescent light bulb?
A four foot tube is about $4.95.
