May 29, 2002 Measuring A Quasar’s Redshift Objective- The objective of this lab exercise is to measure the redshift of a quasar. Inquiries- 22-1a- To find the number of angstroms per millimeter on the photograph I have to do a simple couple of calculations. First, I measured between line 3889 and line 6030. That gave me a total of 76 millimeters. Then, I subtracted 3889 from 6030. This gave me a total of 2141 angstroms. Finally, I divided 2141 by 76mm to …showed first 75 words of 353 total…

…showed last 75 words of 353 total…Absolute Maximum and minimum Velocity with computed redshifts. Data- Please see all inquiries for Data breakdown. Analysis- Please see all inquiries for Breakdown of analysis. Conclusion- In completion of this Lab I was able to determine that the average redshift value was .159 in wavelength change. I also determined from the previous calculation that the Quasars velocity relative to the speed of light was approx. .336 to 2.336. Overall this lab was fairly detailed and required many calculations.
