 In this section we're going to be looking at the electron. Where is the electron located? How does the electron behave? And if the electron is so small and we can't see it, how do we know? We're going to use the Tesla coil for our source of electrons to illustrate. This Tesla coil is taking 120 AC current, you can see I have it plugged in, and converting it to a very high voltage. And this will give us about 50,000 volts of electricity. And then what's going to happen is we're going to pull our bulb, this is just a regular fluorescent tube, and we're going to let the electrons jump from here to here because there's a potential difference. And as they jump from here to here, look at that pretty pink color. That's actually the ionization of the air in between. And then the electrons will enter in the tube, and they will bounce off the fluorescing materials that are painted on the inside of this bulb. So let's see what that looks like. In the tube you saw we produced white light. What we want to do is to pass this white light through a prism and see what happens. So in this section let's look at what makes up white light and what that tells us about light if we can break it up into colors of the prism.
