I was just thinking about my post a while back about the lightbulb. I was wondering how that actually works though. There are so many different types of lightbulbs these days, but how do they all work? None of them work the same way. For example a halogen lightbulb has a tungsten filament. The difference is that they have a halogen based gas around them. This gas captures the tungsten atoms and brings them back making the bulb last longer. Another example is the fluorescent bulb. This has small mercury atoms in it. The electrons flow through the tube and bump into the mercury atoms creating both seeable and fluorescent light. The white filter around the bulb makes most of the light seeable. To see how the rest of the lightbulbs work click the image below.
