Waves and Sound
Jan Mäder, Mary Winn · 2012
Although most of the activities provided for the study of waves and sound involve vibrating objects producing sound, other types of mechanical waves and wave behaviors are included. For each activity or demonstration, ask students what is vibrating to create the disturbance. It is also appropriate to discuss the differences between a pulse and a continuous wave and the differences in the methods of producing them. Have students focus on the transmission of energy along the path of the wave in each example, recognizing that the vibrating object remains centered at its rest position.
