Which Chapter/Sections are covered? Chapters 1-4, the “Fundamentals” were covered on homework 1 (and ALEKS). I do not plan on any direct questions from the fundamentals, the exam is based on content in Chapter 12. All the material on the exam has been covered in one way or another on homeworks 2 and 3. Concentrate on the subject matter emphasized in class and on these homeworks. Come in mentally prepared to answer at least 25 questions, maybe a few more. Yes, there will be calculations, but most of the exam will be theory and concepts. You need to understand the theory and concepts to the level at which we studied it. I don’t expect you to solve the Schrödinger equation, but I do think you should understand what it meant towards modern atomic theory. And, just because you got a homework question right does not necessarily mean you really understand the material. Try explaining the concepts to someone else to see if you really understand. •Bring a pencil(s) and non-graphing calculator to the exam. WE will provide you with an exam copy, an answer sheet (bubblesheet), and any scratch paper that you might need. •You need to memorize the formulas with the green background. They will not be provided. Other formulas might be provided on the front page of the exam although there will be no labeling of the formula. Energy traveling at the speed of light Know what electromagnetic radiation is and how we depict it on the page and conceptually. Know the basics of the entire electromagnetic spectrum (Figure 12.3, shown below). Know the approximate wavelengths for each type of radiation given (LOOK at that figure). Know also, that visible light is in the 400-700 nm range (that’s blue end to red end). Other than the two ends, I do not expect you to know the wavelengths of all the colors of the rainbow – however, you SHOULD know the ordering of the colors (think Roy G. Biv). Use Your Resources - the Internet Type in “electromagnetic radiation” into a google image search. LOTS of good pictures for learning the relative areas of the scale. Do know what type of excitations go with the various radiation types. For example, visible and UV light yield electronic excitations in atoms and molecules while infra-red (IR) radiation really just causes vibrational excitations. The internet is your friend - use it and you can find countless examples of ALL of this material. EM Radiation Equations Know the two basic equations that describe electromagnetic radiation: Know how to use this equations to calculate various wavelengths, frequencies, and energies of photons. Know the two views of electromagnetic radiation: as a wave and as a particle (photons) Do all moving particles have wavelength? Yes. Louis de Broglie said if light can be treated as a
