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 quarter we will study areas of wave mechanics, sound and optics that have applications or relevance to the life sciences.

 

Answer to Final Exam question 18 on version 1, question 3 on version 2:  speakerab.pdf

The table below lists the curriculum and textbook references for the Waves quarter of PHY138-Y1Y. The textbook is “Physics for Scientists and Engineers: A Strategic Approach” by Randall D. Knight, Copyright 2004 by Addison-Wesley. The only chapters we will use in this quarter are 14, 20, 21 and 23. If you have the text in separate volumes, Chapter 14 is in Volume 1, and Chapters 20, 21 and 23 are in Volume 3. Topics that are in bold-italics are direct applications to the Life Sciences.  Extra notes may be 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.
