how does tubelight works?

Answer 1

A fluorescent lamp (tube lights) is a gas-discharge lamp that uses electricity to excite mercury vapor in argon or neon gas, resulting in a plasma that produces short-wave ultraviolet light. This light then causes a phosphor to fluoresce, producing visible light.

Answer 2

The below link is very detailed. But i will tell you in a nut shell.

In the tube contains vapor of quicksilver. When you switch it on, electric goes though the tube, heating up the vapor, increasing the pressure there. The quicksilver molecule then moving chaotically, hitting each other and produce light.

The color of the light you see depends on the fluorescent on the inner surface of the tube.

Answer 3

mercury vapor in the tube is subject to electricity which causes it to ionize. ionization is the electrons jumping away from the atom and the returning. elecricity provides this "jump" and the energy is then released upon returning to the atom. this release is in the form of ultraviolet rays which when they hit a "fluorescent" coating on the inside of the tube causes it to glow ( voila ! tube light )

Answer 4

Are you talking about glow sticks? Well that's a chemoluminescent reaction between dimethylteraphtalate. t-butanol, and sodium salicylate, with hydrogen peroxide as activator.

Answer 5

I assume that's British for flourescent light. Here's a good writeup.
