exp 7 report

[robert zellmer]

Someone asked about how the sketch on page 65.  Here's the following
instructions sent previously.  Using the Word document template you can
make the sketch pretty easily by going to "Insert" and the "Shapes" and
insert (draw) a line and even make it the colors you need for the spectrum.

The calculation on page 66 has to be typed in.

For the top table on page 67 it states to circle the correct answer(s).  You
can do this again using "Shapes" at "Insert".  Alternatively, you can delete
the incorrect answer(s) and leave just the correct answer(s).

*The template MUST be used.  No pictures or scans will be accepted.**

REPORT*:

This is done individually. *NO GROUP work*!!!

There is no "formal" report.  You will turn in the notebook pages before
leaving lab as usual.  This will count as part of the grade.

For this report there is a *report template *on *Carmen *which has the 
tables
on page 63 and pages 65-68.  You *MUST *use this *template* for the report.

Insert a cover page (as usual) and fill in the tables in the template 
(pages 63
and 65-68).  You can use Excel to make the tables on page 63 and replace
those tables in the report template or you can simply type your numbers
directly into the tables.  I would suggest using Excel for at least 
Table 7.2.
Include the graph for the H spectrum.  You don't need a purpose, procedure,
discussion section (unless you need to discuss some sort of errors for 
the data
you collected in part 2 and your graph) or conclusion section. There is one
sample calculation using the eqn. generated from your calibration graph to
calculate a single wavelength for the He spectrum.

For the *graph (calibration curve*):

You need to make a calibration curve to relate your scale readings to
wavelength.  You use the H spectrum to do this.

Look on page 64 (top of page) for an explanation.  You graph wavelength
versus scale reading.  It should be a smooth curve (not a linear fit).  
If using
Excel it will give you an eqn. relating wavelength to scale reading 
(based on
your H spectrum) which you can use to calc. the wavelengths for He by
substituting the scale readings for He.  An easy way to do this would be to
make Table 7.2 on page 63 in Excel (at least the scale readings) and program
your eqn from the calibration curve into the table.   You have to show one
sample calc. on how you get a wavelength from scale reading for He.
Make sure your graph follows the rules for making a good graph.
