The Very Large Array

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

a) The Very Large Array can detect all forms of light.
b)
c)
d) it uses 27 antennas that admit radio waves

Part A-
5: interactions- 36
10: interactions- 66
15: interactions- 272
20: interactions- 276
25: interactions- 346

as the number increases the interactions increase as well, the relationship is exponential because of the leaps in the numbers.

Part B-
5: interactions- 25
10: interactions- 113
15: interactions- 203
20: interactions- 403
25: interactions- 620
the numbers are more linear. They are more accurate because there are more test subjects.

Part C-
1.5ev- 828nm- sent-15 detected- 12
1.8ev- 690nm- sent-15 detected- 12
2.0ev- 621nm- sent-15 detected- 14
2.3ev- 540nm- sent-15 detected- 12
2.5ev- 297nm- sent-15 detected- 13
It's wavelength goes down and the number detected stays almost the same

Part D-
2.2eV- 565nm- H- sent- 15 detected- 8
2.2eV- 565nm- O- sent- 15 detected- 13
2.2eV- 565nm- Mg- sent- 15 detected- 11
2.2eV- 565nm- Na- sent- 15 detected- 11
2.2eV- 565nm- Ca- sent- 15 detected- 10
With all of the gases it stays about the same but with O there is a higher amount detected and with H there is fewer. I don't think you will get the same patterens because the numbers seem to vary a lot.

Notes on Stellar Spectra

1.Absorption spectra
2. closer, because the distance they are from us make them seem to move more than the further ones
3. brightness
4. the middle radiates to the rest of the star
5. intensity is how bright it looks
magnitude is how bright it really is

one task would like to spend my whole life doing is working with people. I just want to make a difference in at least one person's life. at this moment i really don't know what i want to do with my life.

speed of light

Distance between the hot spots 10cm
Wavelength 20cm
Wavelength .2m
Frequency of the microwave 2500000000m
EQUATION c=λ*f .2*2500000000=c
Your calculated speed of light 500,000,000m/s

Electromagnetic Radiation

With out a cell phone, something that uses electromagnetic radiation, my life would be very different. not only would I not be able to call my friends (or my mom when I needed a ride) I would also be unorganized because I wouldn't have the calender in it (which i use a lot). Telling time would also be a hassle because I don't own a watch, and my phone has a built in clock =3.

Blog 3

a. That the rotation is fairly quick
b. It lost energy between going to mars and coming back
c. The five slices are from five different points of mars that the wave hit.
