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

Prepare for test 2 by reviewing assignments A6 - A10 and H6 - H10 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.
