Spectrum and quantum numbers

We started class by discussing about the electromagnetic spectrum. Mr. Lieberman then passed out these glasses to everyone in the room.

He told us to look at the lights in the room with the glasses on. You would see something similar to this.

These are called continues spectrum. The glasses makes the light bend into different colors. Then, he took out a tube filled with hydrogen gas. He put it in a machine that gives off energy. He then turn off all the lights, and this is what we see.

sorry its blurry!

Then, we put on our glasses, and this is what we see.

These are called line spectrum. Different frequency effects different wavelengths. Again, this happen because the glasses bends the light, making them break through its components.

We then go over the notes. We went over the Spectrum all the way to the quantum numbers. When there is energy, electrons jump up and then back down. When the electrons jump down, they release energy/light. We then went over quantum numbers. Here's a video explaining the quantum numbers.

Feel free to email Mr. Lieberman or go to the TLC if you still do not understand this.

HOMEWORK: Quantum Number worksheet and go on Moodle for a new schedule for this unit.
