Why is a glowing bulb hotter than a tube light?
Incandescent bulbs work by heating a filament (usually made of a tungsten compound) until it glows white. Up to 90% of the energy needed goes to waste in the process, since humans can't see into the infrared. Fluorescent bulbs work by exciting the molecules of mercury vapor into emitting ultraviolet light, which is then absorbed by the white phosphor coating and re-emitted as visible light. It's much more energy efficient -- and more importantly, nowhere near as hot.
When zinc carbonate is heated on a dry test tube what observation is seen?
when zinc carbonate is heated it' white colour changes to yellow . And when it is cooled it again changes to it original colour
What will happen when you thrust a glowing bamboo stick inside the test tube with oxygen?
The glowing splint will relight if you place it in a flask with oxygen. Scientists do this as a test for oxygen so if it relights, then that means the flask contains oxygen.
What happens when you thrust a glowing bamboo stick inside the test tube?
If only oxygen is in the test tube, it may burst into flame.
What is a example of phosphorescence?
its the souce of light offered from a tube light.... its white light, with all spectrum of colours
Why tube light glow in white colour?
Tube lights glow in white color because they contain a phosphor coating on the inside of the tube that emits white light when excited by electricity. The phosphor coating helps to convert the ultraviolet light produced by the electrical current into visible white light, resulting in the tube light emitting white light.
Does a tube light emit multiple wave length?
The answer completely depends on what's glowing inside the tube and producing the light.
Why won't the center of a fluorescent tube light if the ends are still glowing?
you need to replace a ballast
What are science fair projects the can be done in a day?
go to you-tube and search up glowing light you could do something with that.
What is the difference between the normal light globe and a fluorescent tube?
"Normal" light globes use a glowing filament, heated by the current. Flourescent tubes ignite a gas within a tube, using an arc.
Why light emitted by a bulb is yellowish in colour but from a fluroscent tube is white?
The color of light emitted by a bulb is determined by the material of the filament which usually emits a warm, yellowish light. Fluorescent tubes produce white light by using a phosphor coating on the tube that converts UV light into visible light of different colors, resulting in a more natural white light.
What do t5 slimming pills look like?
They are white or red in colour and are tube shaped.
What are neon signs made out of?
They are made out of glass as a the tube and there is no active filament what actually creates the glowing is there is a gas inside the tube and the electricity that runs to it creates the gas to ionize which creates light.
What is the test for oxygen and the result if oxygen is present?
If a test tube is filled with oxygen when you put a glowing splint into it, the splint will relight. (To make the splint glow you have to light it then blow it out and put it into the test tube immediately.) Hope this helps. XD XD
Why tube light glows white?
due to presence of Mercury
How is light generated through a spectrim?
If / when light is generated by heating, a continuous spectrum is generated. A small portion of this electromagnetic spectrum may be detected by humans.When light is generated by creating a plasma, then only the spectral lines particular to that substance are generated.You can perform this simple experiment yourself. If you hold a CD at an angle towards an incandescent lamp, you'll see a complete colour spectrum - there will be no breaks between the colours.If you repeat the experiment with a fluorescent (or CFL) lamp, you'll see several separate colours, with clearly no continuous grade of colour between them.This is because the fluorescent tube actually generates a plasma inside it, and the UV light from the plasma will excite the phosphors (the white coating in the tube) on the tube. It needs several phosphors to approximate the colour of white light, but it is only an approximation.
