What are waves? What different kinds of waves are you aware of? What characteristics do waves have?

Some Definitions and Basic Concepts

 * * Traveling Waves || * Reflections & Interference ||
 * * Standing Waves || * Types of Waves ||

Conceptual Questions

 * 1) What is the relationship between velocity of propagation, frequency and wavelength?
 * 2)   When a wave moves from one medium into another, what happens to its velocity, frequency and wavelength?
 * 3)  What is a sonic boom?
 * 4)  When a wave reflects off a boundary, what determines whether it is or is not inverted?
 * 5)  What determines the speed and direction of propagation of any wave?
 * 6)  From her lips to his ears.” How does our “tin can phone” work?
 * 7)  <span style="FONT-FAMILY: 'Arial','sans-serif'">How are longitudinal and transverse waves different? How are they the same?
 * 8) <span style="FONT-FAMILY: 'Arial','sans-serif'"> <span style="FONT-FAMILY: 'Arial','sans-serif'">What does tuning a stringed instrument do? How does that work?
 * 9) <span style="FONT-FAMILY: 'Arial','sans-serif'"> <span style="FONT-FAMILY: 'Arial','sans-serif'">When a wave moves from one medium into another, does all the energy continue to propagate in the same direction?

You will need to explore the site to make good use of it. http://www.kettering.edu/~drussell/demos.html A site about acoustics and vibrations. Lots of the material in the site is applicable to general waves not just sound waves. http://id.mind.net/~zona/mstm/physics/waves/interference/intrfrnc.html A good site about interfearance and related topics. http://www.glenbrook.k12.il.us/gbssci/Phys/Class/waves/wavestoc.html A Useful waves Tutorial site. http://csd.k12.nh.us/~chflem/0001C251-70E903AC.0/torque.ppt A good overall presentation explaining waves. A little bit of everything. http://physics1.scienceyamamoto.com/docs/Unit_5/physics01_unit05_notes_waves.swf Another good presentaion about waves.

Assignment #1
Please go to http://hippocampus.org/myHippo/?user=abuchanan and use the bookmarks on the left side of the screen to open the "Intro to Waves" and "Wave Energy" activities. (Hold down the "command" key when you click the link so Safari will open it in a new tab.) Use this study guide with these interactive lessons.

Assignment #2
It is time to start collecting what you learning in Assignement #1 and use it to build our class Wiki. Please download Assignment #2 for details.

Before starting assignment #3, please do the following: It is time to start "K"ollaborating on your Wiki pages. Please down load assignment #3 for details. Please try to read it. This assignment is different than anything else you have done before.
 * Put your name on the top of all your pages. Put "by [your name]" See Traveling Waves as an example of how to do this.
 * Team leaders should put "by [your name] and Team" just below the title on team pages.
