Nature of Waves Vibrations or oscillations are closely related to waves. Waves are created whenever objects vibrate or oscillation. Periodic Motion * A repeated motion that occurs back and forth over the same path at regular intervals. Examples: * A Child on a swing * A wrecking ball swaying to and fro * A swinging pendulum of a grandfather clock Simple Harmonic Motion (SHM) * Is a type of motion along a straight path in which the acceleration is proportional to the displacement

Florida Institute of technology | FSO Report | | | Rami nahas | 4/29/2011 | | Free space optical communication is the most growing communication because it is easy to install and has a high speed because the signal is transmitted in the air. So that will introduce the atmospheric affect in the optical wave propagation. Atmospheric turbulence causes fluctuations in both the intensity and the phase of the received signal. So we need to study the effect and the limitation if we

INTRODUCTION Radiation‚ flow of atomic and subatomic particles and of waves‚ such as those that characterize heat rays‚ light rays‚ and X rays. All matter is constantly bombarded with radiation of both types from cosmic and terrestrial sources. This article delineates the properties and behaviour of radiation and the matter with which it interacts and describes how energy is transferred from radiation to its surroundings. Considerable attention is devoted to the consequences of such an energy
