  1. How are mechanical waves produced?


  1. What is a medium?


  1. Which of the following are mediums through which waves can travel? Circle all that apply.

Rock Water Air




  1. A transverse wave causes the medium to vibrate at ____________________ angles, or perpendicular, to the direction of the wave.




  1. Draw perpendicular lines.



  1. What is an example of a transverse wave?



  1. A longitudinal wave is a wave in which the vibration of the medium is ____________________________________ to the direction the wave travels.




  1. Draw parallel lines.



  1. What is an example of a transverse wave?



  1. What is a compression?



  1. What is a rarefaction?


  1. Label the compressions & rarefactions of each wave. Are these longitudinal or transverse waves?







  1. What is a surface wave? Give an example.


  1. Label the mechanical waves in the diagram below.
