Luminosity = Magnitude = brightness

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

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

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

1. Hydrogen

2. Helium 667 587 501 492 471 447 402

3. Carbon 412 470 488 500 510 538 567 592 605 659 680

4. Oxygen 410,413,423,440,442-450, 478-480 –blues red-640,650,668,672 Green-520, 533, 550 yellow-593,599 , 604 orange-610,618,630
