3. Compressional waves(Right)
How does a compressional wave work?
2) Which kinds of waves travel as compressional waves?
3) What features do compressional waves have?
Compressional or longitudinal waves move parallel to the direction of energy transport.
Mechanical waves, need a medium
-P waves (Earthquake waves)
-Sound waves
3. Compressional waves have amplitude, frequency, and wavelength; however, they are measured differently than transverse waves. Amplitude in a sound wave is VOLUME.

4. Compression = pushed together Rarefaction = spread apart

5. How are mechanical and electromagnetic waves different?
