Chapter 11: Vibrations and Waves Objectives

• What is Simple Harmonic Motion and why is it important?
  
  
• How can I use Conservation of Energy to study this motion?
  
  
• What is Periodic Motion and how do I find the Period and Frequency of this motion?
  
  
• How is a Simple Pendulum, a mass on a cord, like a mass on a spring?
  
  
• What is Damped Harmonic Motion and Resonance and why did that Bridge fall down anyway?
  
  
• Where do Waves come from and what are Periodic Waves?
  
  
• Are the major types of waves Transverse and Longitudinal and what are they?
  
  
• How do waves Transmit Energy?
  
  
• In what ways do waves interfere with each other, what is the Principle of Superposition and how does it explain Standing Waves.
  
  
• I have heard of Refraction and Diffraction. What are they?

NOTE:

The recommended system requirements to use the applets in the Physlet® Problems modules are:

• a Pentium 90 with 16MB RAM or Power Macintosh with 32MB RAM
• either Netscape 3.0.3 and higher or Internet Explorer 4.0. Internet Explorer 3.0/AOL browser does not work!
• Your internet connection should be through your school's local area network. Using a 28.8 modem will result in dramatically increased load times.
