Unformatted text preview: There is another way to find d and R with only relative angles. See if you can figure out how to do this. Tasks 4-5: Derive and understand equations 1-3. Task 6: Measure the transmitted intensity as explained. If you use care, you can read the angle from the goniometer without the laser and mirror. Task 7-8: (Duplicated in writeup). Ask your instructor for the focal length. Task 9: Determine the separation between the main and satelite rings (the eyepiece mechanism is attached to a micrometer) and corresponding wavelength differences. Task 10: Derive equation 6. Task 11: Describe your observations of the hyperfine lines of Hg (from Task 9) with help from the information in section 6 of the writeup and from p241ff of Preston and Dietz. Misc. Hints:- This experiment is much easier with rooms lights off.- A reasonable PMT HV setting is ~400V....
