EXAM 2 REVIEW QUESTIONS
Exam 2 will cover Chapters 26.4 through 30 in the Pasachoff text and the
corresponding Online Journey Through Astronomy material as shown in the
course syllabus. The online text includes self
quizzes which are excellent for review. Some more questions similar to the
ones you can expect on the exam can be found here, for each chapter.
The exam will contain only multiple choice or matching questions, but
the review also includes some fill-in-the-blank questions.
