FINAL EXAM STUDY GUIDE Astronomy 104 Fall 2006
Format of the final exam
Approximately half of the exam is new material since exam 3, and the other
half is everything else.
In general the format of this exam will be very similar to the other exams.
Please note that there is a section on the HR diagram similar to what was on the
first exam, and a section on evolutionary paths on the HR diagram similar to
what was on the second exam.
- 10 image identification (see below)
- 10 - 15 multiple choice. Note: the multiple choice questions are just on
the material since exam 3
- 15 - 20 very short answer (answer using one or two words)
- 8 - 10 questions requiring several sentences to answer
- 20 - 25 points in a section of miscellaneous short answer: there are questions which can be
answered in lists or diagrams or matching. Included is a section
of matching characteristics with objects, a section on the HR diagram similar
to exam 2, and a section on evolutionary paths on the HR diagram similar to
exam 3.
- 1 - 2 long essay ( one page answer)
- 4 -5 problems
Image identification: For part of this you will be asked to identify
different types of objects such as: emission nebula, reflection nebula,
dark nebular, open cluster, globular cluster, and planetary nebula. You do
not need to know an objects proper name, i.e. you do not need to know the name
"the Ring Nebula" but you should recognize it as the type planetary nebula. Look here for examples of the
different
types of objects.
You will also need to identify the major types of galaxies, e.g. spiral,
barred spiral, elliptical, and irregular. You do not need to know the sub types
(e.g. a,b,c for spirals and 0 - 7 for ellipticals). Look here for examples
of galaxy types.
List of topics (by chapter) for the final. This list includes only the
material covered since exam 3. You should look at the lists for exams 1, 2&3.
