What is in a florescencent light tube, from a chemistry stand point?
Answer:
A fluorescent lamp 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...
Mercury vapor, when subjected to an electric field emits UV light. When that hits the phosphorus it emits light because it is florescent.
FROM CHEMISTRY POINT OF VIEW
THE TUBE ARE CONTAINING NOBLE GASES , AND DUE TO THE HIGH VOLTAGAE IN WHICH IT GONNA PASS THE TUBE THE NOBILE GAS WILL EXCITE TO HIGHER LEVEL OF ENERGY AND WHEN THE ELECTRON COMING DOWN T GROUND STATE THEY EMITTE THIS TYPE OF LIGHT
