2. How do waves interact with one another?



3. What are the characteristics of sound waves?

4. What is a mechanical wave and what are its characteristics?



Assignment 2
==In your own words give the definition for the following vocabulary words for this section. Post you thoughts to the discussion board for this page. Please remember I want to know what you think these words mean. ==

Simple Harmonic Motion Amplitude Period Frequency Medium Transverse wave Longitudinal Wave Crest Trough Constructive interference Destructive Interference Standing wave Node Antinodes Compression Rarefaction Pitch Doppler Effect Intensity Decibel Spherical Waves Plane Waves Natural Frequency Forced Vibration Resonance Fundamental Frequency Harmonics Overtones Beats

Assignment three to be presented in class:
==Presentations: Give a 2-3 minute presentations on your assigned topic. You may use power-point visual aids and outside sources in-order to insure the classes understanding of the topic. ==

Our Goals and Outcomes: Identify beats and the Doppler Effect result from the characteristic behavior of waves. || Identify that sound is a longitudinal wave whose speed depends on the properties of the medium producing it Show that waves have characteristic behaviors, such as interference, diffraction, refraction and polarization. || Projects and Demonstrations:
 * __ Initial Understanding __ ||
 * Identify that wavelength, frequency and wave speed are related
 * __ Developing an Interpretation __ ||
 * Describe how waves carry energy from one place to another.
 * Describe how waves carry energy from one place to another.
 * Describe how waves carry energy from one place to another.
 * __ Making Connections __ ||
 * Apply engineering skills to show that transverse and longitudinal waves exist in mechanical media, such as springs and ropes, and in the Earth as seismic waves. ||
