Test 2 will cover the material presented in modules 6 - 10.  

You must be able to:

• Define current density, current, resistance, and resistivity.
• Solve simple circuit problems involving voltage, current, resistance and power.
• Find the equivalent resistance of resistors in series and in parallel.
• Use Kirchhoff's rules to analyze DC circuits.
• Calculate the magnetic force on moving charges and current-carrying wires in a uniform magnetic field.
• Calculate the torque on a current loop (magnetic dipole) placed into a uniform magnetic field.
• State Ampere's law.
• Calculate the magnetic field produced by current carrying wires in simple geometric configurations.
• Qualitatively describe properties of magnetic materials.
• Correctly analyze situations in which an emf is induced by a changing magnetic flux.
• Calculate the magnitude and determine the direction of the emf induced in simple circuits.
• Explain the concept of self inductance.
• Explain how devices such as electric generators, transformers, maglev trains, magnetic brakes, etc, work, based on Faraday's law.
• Describe the radiation pattern produced by an oscillating charge.
• Distinguish between unpolarized and polarized light.
• Calculate diffraction snd interference patterns produced by a single slit, two slits, and a diffraction grating.
• Work problems involving interference from thin films.
• Calculate the maximum resolution of optical instruments.
• Work problems involving the laws of reflection and refraction.
• Use the mirror equation to predict the position and magnification of real and virtual images formed by flat, concave, and convex mirrors.
• Draw ray diagrams.
• Use the lens equation to predict the position and magnification of real and virtual images formed by thin concave and convex lenses. 

Prepare for the test by reviewing assignments 13 - 24.

Please take the practice tests on Canvas.  You can take these tests as often as you want.  No score is kept.  Each problem contains hints for incorrect answers.

Formulas

The first page of test 2 is the formula sheet.  During test 2 you can use this formula sheet, but you can also use other printed (on paper) reference materials of your choice.  You however must work alone.  Please do not consult with another person while you are taking the test.
