Document Summary
Propagation of a disturbance: two mechanisms: mechanical waves and electromagnetic radiation, both depend on waves, all mechanical waves require: A medium containing elements that can be disturbed. Some physical mechanism through which elements of the medium can influence each other. The elements of the string are connected together, so that the wave can move: pulse exploration first, because waves are simply periodic pulses, each disturbed element moves in a direction perpendicular to the direction of propagation. No part of the string shown beside ever moves in the direction of propagation. Examples of longitudinal waves are sound waves: some waves exhibit both transverse and longitudinal wave characteristics: The same as that of the function sin plotted against . Is the simplest example of a periodic continuous wave, can be used to build more complex waves. The movement is the motion of the wave. Each element moves up and down along the y axis in simple harmonic motion.
