Types of Telescopes Chandra

a)the EM radiation range targeted by the following telescopes (there may be more than one)
X-Rays
b) a picture generated by this telescope (or, if it is a prototype, a schematic of the design)

c) how old the light coming into the telescope is, in light years or light minutes

d) if the telescope uses mirrors, CCDs, lenses, or a combination of all.
It uses mirrors.

Reflecting vs. Refratcing Telescopes

1.) In Newton's telescope you could see the color spectrum.
2.) It was showing that the earth wasn't the center of the universe like everyone had previously thought and the church didn't want to believe that.
3.) It paved the way for future astronomers.
4.) Changed the way we look at the solar system
opened the door to be able to research more things
allowed us to look at space more clearly

Notes on Stellar Spectra

1.) A hydrogen light spectra are more likely to appear on earth.
2.) Closer stars because the difference in position is more noticeable.
3.) Apparent brightness
4.) Hydrogen, many atoms fuse together to make helium which burns very hot and the interactions keep multiplying as more and more helium atoms are made, throwing off a hydrogen atom.
5.) Intensity is how bright the star appears and magnitude is how bright it actually is.

Escaping the Sun

Part A
Layers Interactions

5 22
10 212
15 182
20 265
25 822

As the number of layers goes up the number of interactions usually goes up. The only exception is for 15 layers. I don't see a linear or exponential pattern in the numbers.
Part B
Layers Interactions

5 30
10 99
15 250
20 408
25 639

The number of interactions went up per layer. More accurate because the more points of data you have to test the more accurate your results will be.

Part C
Energy(eV) Wavelength(NW) Photons sent: Photons Detected

1.5 828 15:12
1.8 690 15:11
2.0 621 15:10
2.3 540 15:11
2.5 497 15:12

1.) It gets smaller.
2.) The number increases consistently with the exception of the wavelength of 2.0, where it decreased then resumed getting larger.

Part D
Energy(eV) Wavelength(NW) Gas Atom Photons sent: Photons Detected
2.2 565 O 15:4
2.2 565 Mg 15:13
2.2 565 Na 15:9
2.2 565 Ca 15:13

1.) The different gas atoms have different consistences and that will effect the number of photons detected.
2.) A line spectra would have to be seen as if the element was used as a light bulb.
3.) Yes you would get the same patterns because the elements are still the same you would just have a higher wavelength.

Annie Cannon and the Spectra

As of right now i would like to go to college and end up running my own business.

What is it?

To me it sounds like a nuclear blast.

1. The way the patterns look and the how powerful the blast was sounds similar to what happened in Japan.

2. A UFO sounds ridiculous.

3. The way certain things are flattened and the amount of radiation sounds like a nuclear bomb.

Electromagnetic Radiation

Cell Phones- Cell phones have become a way to do many things. Without my phone I wouldn't be able to keep in touch with many of my friends or family. It makes life more convienent and accessable. With all of the things you can do with cell phones now many people would be lost with out them.
