1. Add to table of contents:
Color the Spectra Pg. 8
Electromagnetic spectrum Pg. 9

2. Herztsprung-Russell Diagram
Attach to the top of page 9.

3. Luminosity = Magnitude = brightness

4. Electromagnetic spectrum
Stars emit all forms of electromagnetic energy.
We can only see a very small part of it = visible light = colors.

5. Draw on page 9
Short wavelength
Long wavelength

6. Each element, when illuminated, gives off an unique set of spectral lines called a “spectral fingerprint”.

7. You need the paper from Ms. Stark to do the following pages:
Create the spectral fingerprints of the following elements:

8. 1. Hydrogen

9. 2. Helium

10. 3. Carbon

11. 4. Oxygen 410,413,423,440, , –blues red-640,650,668,672
Green-520, 533, yellow-593,599 , orange-610,618,630
