A longitudinal wave is a wave in which the particles of the medium are displaced in a direction parallel to the direction of energy transport. If five waves are produced in one second, then the time period of one wave is a. I think it is directly proportional, because if you look at some displacement-time graphs, you will see that as the frequency increases, amplitude also increases. Hence cos(2/ * (x - ct)) represents a forward propagating wave . 2. Light consists of electromagnetic waves. The larger wind speeds create more shear. National Geographic Headquarters B & D. D.
