how a ccd works
computer reads the voltage charge. Light comes in and hits the metal and gives you the charge.
Two Sides To Every Story
I believe there is life out there other than us. If God can make life on Earth why wouldn't he make it somehwere else? If he can make Earth a place where things can live i am sure he would do the same somewhere else. It is just a matter of us being able to find it.
Chocolate Lab
Distance between hotspots = 12 cm
1/2 wavelength = 12 cm = .12 m
Frequency = 2.5 * 10^9 Hz (1/s)
c = speed of lightx = 1/2 wavelength
f = frequency
Equation -> c (m/s) = 2 * x (m) * f (1/s) -> c = (2) (.12) (2.5 * 10^9)
Experimental c = 6.5 * 10^8 m/s
Actual = 2 * 10^8 m/s
1/2 wavelength = 12 cm = .12 m

escaping the sun
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.
