The Waves Section of PHY138Y – 2005/06

Waves are the results of oscillations which convey energy to their surroundings.  Some examples include water surface waves, waves on a string, sound and light.  In this section we will study areas of wave mechanics, sound and optics that have applications or relevance to the life sciences.

Solutions: Web Format / PDF Format – includes reasoning for multiple choice problems.

Syllabus

The table below lists the curriculum and textbook references for the Waves section of PHY138Y. The textbook is “Physics for Scientists and Engineers: A Strategic Approach” by Randall D. Knight, Copyright 2004 by Addison-Wesley.  Topics that are in bold-italics are direct applications to the Life Sciences.  Extra notes on these topics are posted on this web-site near the time of the lecture. Textbook sections that are listed below are examinable; those that are not listed below are not examinable unless otherwise announced.

It is likely that the listing will change somewhat as the course proceeds. After the class has been given, the topics and text references will be updated if necessary and a link will appear in the More column to a more detailed summary of the class.
