Test 2 will cover the material presented in modules 7 - 12.  The test is an 90 minute test and it allows one submission. There are 30 problems.  You can omit 5 problems or you can answer all problems and the best 25 answers count.  The highest score you can get is 25/25.

You must be able to:

• Work problems involving the laws of reflection and refraction.
• Draw ray diagrams.
• Use the mirror equation to predict the position and magnification of real and virtual images formed by flat, concave, and convex mirrors.
• Use the lens equation to predict the position and magnification of real and virtual images formed by thin concave and convex lenses. 
• Calculate diffraction and 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.
• Calculate the energy and momentum of the photons.
• Work problems involving the photoelectric effect.
• Calculate the deBroglie wavelength of free particles.
• Calculate the energy levels of the hydrogen atom and interpret the emission spectrum of hydrogen.
• Predict some of the properties of multi-electron atoms,
• Describe the essential features of a LASER.
• Describe the static properties of nuclei and the radioactive decay of certain nuclei.
• Describe fission, fusion, and principles of nuclear energy generation.
   

Prepare for test 2 by reviewing assignments A7 - A12 and H7 - H12 and the problems on the summary slides.

Please take practice test 2 on Canvas.  You can take this test 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.
