Spectroscope Lab

This is not a formal lab report but it must be typed . Your lab report will consist of three sections: Results, Discussion and Questions. The lab report must be typed using a 12 point font. Reports not typed will lose points. All parts to report must be typed with correct formatting. No excuses. Cursive or ornate fonts are not acceptable. Be careful with spelling and grammar. Poor spelling and grammar detract from a reader’s overall impression of the report. Spelling and grammar errors will lose one point each.

Your report will be graded out of thirty points possible as follows:

Results. (10 points) This section should include your results:

Describe the construction of your spectroscope.

Describe the spectra generated by your spectroscope with the three different gas generation tubes.

Discussion (10 points):

Describe how you think your spectroscope could be improved.

Questions. (10 points – 2 points per question) Answer the following five questions:

1. What was the first element identified with a spectroscope?

2. What wavelength of light will be produced by an n=3 to n=2 transition in a hydrogen atom and what color will this light be.

3. What is a diffraction grating?

4. What is the difference between a spectrophotometer and a spectrometer (spectroscope)

5. Wood often burns with a yellow flame. Why?

Appearance, Spelling and Grammar More than one spelling error and you will lose a point. For major grammar errors (sentence fragments, run-on sentences, comma splices, etc.), you will lose a point. You will lose points for appearance if you incorporate non-typed material into your report or if you use non-standard paper (e.g. notebook paper) in your report.
