Document Summary
*represent in visual -> wave motion using quantity pictures -> graphs. *wave function -> model the motion and structure of a wave in mathematical way. *relation between characteristics of wave and the medium through which it travels. *reflection and transmission of a wave -> encounters the boundary of a medium. *the propagation of a disturbance through a medium with a well-defined speed. *matter is not transferred, but energy is transferred. 2)distribution in medium vs local perturbation of an element. *complex wave: surface water waves exhibit a combination of transverse and longitudinal waves. *electromagnetic waves: these waves do not requires a medium through which to travel, they are disturbances of electric and magnetic fields which propagate each other. *we have three variables (y, x and t), and we would like to understand the relationship between them. We can use graphs to show the relationship: y vs x:
