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.
