Practice problems - without solutions
Practice problems - with solutions:
Light - note in problem 2 the units are km not m
Homework solutions:
Chap 4 - note in 4b answer is 0.4 X 0.25 = 0.1
Chap 16 - note the typo - problem "9" is really problem "5"
Extra credit: There is only one form of extra credit offer in this class. For each exam I will post links to three recent discoveries in astronomy. Choose one and write a 1 to 1.5 page (double spaced, normal size font and margins) analysis of the discovery IN YOUR OWN WORDS (if you absolutely feel the need to quote from the article you must put the words in quotation marks and don't quote more than one sentence). In order to receive full credit (10 pts added to your exam score) you must clearly do the following:
1) Summarize the discovery or accomplishment in
your own words in such a way that I know you
understand what you wrote (Essentially what was discovered/accomplished, who
discovered/accomplished it, and how was it discovered/accomplished).
2) Explain the relationship between the discovery and the material covered in
class for that exam (Why is this article relevant?)
3) Briefly explain why you chose it over the other two choices (Any reasonable
explanation is acceptable here).
Your analysis should also be proofread and use proper English.
If it is not clear to me that you answered all three parts you will not receive
full credit (you might want to make it easy on both of us and actually number
the three parts in your paper - that way it's very clear that you completed the
task).
Very important note: You must
hand in your paper at the BEGINNING of the exam period. You cannot wait until
you receive your exam back and then decide you need the extra points.
