We have observed a number of common student confusions in the area of waves on elastic strings. Based on our research, we have developed student-centered instructional tutorials using interactive video tools on the computer. We will demonstrate some of these materials and discuss their effectiveness. Proceed to talk . The topic of waves is of fundamental importance for understanding nature.
Students make common errors.
Important case where students encounter a situation in which global and local effects are not the same. To understand sound, physical optics, quantum mechanics, and other more advanced topics, students must understand this material. A disturbance propagates through a medium without permanently displacing elements of the medium. Speed of propagation depends on the medium. Superposition of waves is the vector addition of displacement due to each wave.
