pretty much know how light bulbs work- I did a whole science fair project on them. Electrons go in one wire, the hit the tungston atoms, causing them to vibrate and heat up, and it raises an electron to a higher shell. When the electron falls back down, it releases a photo to compensate for the decrease in energy. Now I am having an aurgument with my science teacher (regular occurance). He says that the same amount of electrons that go into the filament come out. I disagree, and say that this is not posible because electrons carry energy, heat is energy, and light is energy. The same amount of energy can't come in and go out of something while CREATING energy(not possible). I say that some must be lost (electrons). Could someone please give me an explenation one way or the other?
