Unformatted text preview: March 5 th , 2009 Astronomy 100 Dr. Warner Review for the 2nd midterm exam DISCLAIMER: THESE NOTES SHOULD HELP FOR THE PREPARATION OF THE SECOND MIDTERM EXAM. THEY INDICATE HOW TO DISTINGUISH THE ESSENTIAL FROM THE LESS ESSENTIAL MATERIAL. HOWEVER, THEY ARE NOT MEANT TO BE A COMPLETE LIST OF THE ESSENTIAL MATERIAL. CAVEAT EMPTOR.

A good understanding of the early parts of chapter 5 is essential to the rest of the exam and therefore you should go over this material again: What waves are, and the meaning of frequency, period and wavelength - and how they are related to wave speed. Diffraction and interference, and the effects of wavelength and aperture size on diffraction. The nature of electromagnetic waves: the spectrum, light as a wave. You should know the names of the various kinds of electromagnetic radiation, and be able to order them according to wavelength, and you should know the approximate wavelength of visible light....
