Hints for Test II

• As usual we should have time the day before the test to review for the test. Come to class with questions! (Stump the instructor day!)
• No sheet of equations.
• Constants will be provided, as will equations needed from last semester.
• You must show the instructor an empty calculator memory before the test starts.
• Any interesting material from these chapters not covered in class is a possible bonus question.
• Homework is not posted until after the due date. You may get half credit for late homework (due the week after the test at the latest).
• Instructor notes for this material (this doesn't include everything- you will still need to study your text- but does summarize most of the material). PDF version.
  
• The main concepts:
  • You should be able to find the electric potential of a set of charges and understand the relationship between electric potential and potential energy. Don't get potential (a scalar) confused with field (a vector).
  • You should be able to find the electric potential from an electric field and also an electric field, given an electric potential.
  • You should be able to apply Faraday and Lenz's laws.
  • There could be a question about Maxwell's equations.
  • You should be able to recognize a sine or cosine description of a wave.
  • You should be able to recognize a generic wave equation and its solutions (sine and cosine).
  • You should be able to find the Doppler shift for light and sound (equations will be provided on the test for both cases).
  • A question about the torque and energy of a dipole (both electric and magnetic) and/or the electric and magnetic properties of matter could appear.
• The following will be put off to Test III:
  • Interference and/or diffraction problem(s), review carefully the homework problems on this material.
  • You should understand and know how to determine the limit of resolution for an optical instrument.
  • Questions about the Fourier Series.
• Any interesting material from these chapters not covered in class and questions about lab exercises are possible bonus questions.  Potential bonus questions may include:
• What is dispersion?
• What is optical activity?
• What is paramagnetism?
• What is ferromagnetism?
• What is diamagnetism?
• Any material we covered which does not appear on this test could appear on the final.
• Obviously you will want to review the problems we did in class, homework problems, and examples in the book. You may want to look at the homework solutions I have posted; even if you got a problem right the solutions may show you a short cut or clever trick. Plus: extra credit for the first person to point out an error in the solutions to me.

Past tests.

• NOTE: From year to year we cover slightly different material so you may see things in past years that were not covered this year. Conversely you may see things on this years test not covered in previous years.
• ALSO: Due to limitations with html formatting, not all figures and equations are available.
