Question

If you have ever seen a fluorescent light bulb break, you know that the inside looks very different from a regular light bulb. See if you can explain this difference.

Answer 1

In a regular light bulb, there is a filament which lights up.  It is surrounded by inert gas so the filament lasts longer.  In a fluorescent bulb, electricity excites mercury vapor in argon or neon gas resulting in a plasma that produces ultraviolet light which causes a phosphor to fluoresce producing visible light.

Answer 2

Inside it has been coated with, normally mercury or other highly reflective material, to get more brightness. And they are filled with fluorescent gases like neon, which are more active when heated. Heated ions moves very fast inside, spreading the light, uniformly when electricity is passed.
