A. Photon # layers Interactions
5 24
10 157 as the number of layers increased
15 174 so did the number of interactioins
20 479
25 947
B. Diffusion the data is about the same. the date is
5 31 more accurate because there were more
10 106 photons and it took the average number
15 233 of interactions.
20 433
25 706
c. ev nm photons sent photons detected
1.5 828 15 14 the wavelength goes down. it
1.8 690 15 8 also goes down.
2 621 15 13
2.3 540 15 11
2.5 497 15 11
d. wavelength gas atoms photons sent photons detected
2.2 565 O 15 14
2.2 565 Mg 15 13
2.2 565 Na 15 9
2.2 565 Ca 15 13
2.2 565 H 15 11
It didn't have much of an effect of the number detected.

Telescope Types

Because our eyes cant pick up things such as heat spots and cold spots and infrared.
Spitzer
a)10 x 8 degrees (about the area of your fist held out at arm's length).wavelengths of 3 and 180 microns (1 micron is one-millionth of a meter).
c)6,500 lightyears away
d)The spitzer telescope is a reflector using a Beryllium metal mirror.

Annie Cannon and the spectra
If there was one thing i could spend my entire life dedicated to doing, lying on my couch watching t.v. would have to be it. Watching t.v. is the one thing that never gets old and if I could just do that my entire life I would be happy with what I was doing. It would also be something that made sure something new was going on every day and it wouldn't get old.
Notes On Stellar Spectra
1.It is most likely Fission
2. Closer so you can tell when their positions change
3. Brightness of the star
4. Emission, when something is given off and absorption is when something is absorbed
5. Magnitude is how bright the star actually is, and intensity is how bright you see it

-Any mishaps with nuclear waste can rendor areas unhinhabitable.
-Every time a bomb is made, radioactivity is released into the air and water.
-Wipp was created in southeast New Mexico for nuclear waste disposal in caves 1/2 mile underground.
-Plutonium is the most toxic substance known to man. 1 lb. of it spread across the world is enough to kill everyone. Plutonium is a daughter product of nuclear waste.
-The amount of acceptable dose of radiation has been lowered for workers in nuclear plants. It is now 5 rehms which is the equivelant of 1,000 x-rays of bone marrow.

Galileo vs. Newton's telescop
Newton's telescope could magnify objects better. It was the first of its kind. Seeing in light, seeing in color, and the first working reflecting telescope.
Galileo's telescope watered out the color because of the thick glass lenses.
