Honors Physics: Objectives and Schedule

Last updated: February 15th, 2011

Unit 10 – Superposition and Standing Waves Chapter 16

Text College Physics, by Randy Knight, Brian Jones, and Stuart Field, Pearson/Addison Wesley, 1st edition, 2007.

Student Learning Objectives  Understand the principle of superposition  Understand how standing waves are generated  Calculate the allowed frequencies and wavelengths of standing waves on strings and standing waves of sound waves in tubes and pipes  Understand the difference between constructive and destructive interference and how the interference of two sources produces a pattern f constructive and destructive interference  Calculate beats

Homework

We are using an electronic homework system from Mastering Physics (MP). All text based homework is to be downloaded from, solved, and the answers submitted on-line to www.masteringphysics.com . DRS problems will also be given out in class and will need to be turned in. Mastering Physics problem will be denoted by MP and the appropriate day number. See the Expectations and Procedures document for penalty details on submitting late work.
