1. Briefly describe Keplers three laws of planetary motion. How did Newtons laws of motion and law of universal gravitation validate Keplers laws?

2. List the parts of the electromagnetic spectrum. What types of telescopes are useful from the Earths surface? What can they observe?

3. Explain how light is produced at the atomic level. Distinguish between emission, absorption, and continuous spectra. What can absorption and emission spectra tell us about stars?

4. Why do modern astronomers place telescopes in orbit about the Earths atmosphere? What types of objects can be observed from those telescopes that arent visible from the Earths surface?

The use of outside sources is optional, but you must provide citations and references in APA format for any sources you use, including the textbook. Lack of proper citations and references and/or poor grammar and spelling could result in a grade deduction of 5 to 15 points.
