  • P and S waves.
  • Wave reflection.
  • Standing waves.

Learning Goals

P-waves with a slinky
Learn about and visualize:

Context for Use

Use in an introductory geoscience course where wave properties are important. Examples of such courses include Geology, Oceanography, or Atmospheric Sciences.

Teaching Materials
