College Physics III - Oscillations and Energy

Periodic vibration of an elastic solid or fluid constitutes an oscillation. Oscillations following simple harmonic motion are of particular interest as this type of motion is common in nature. Waves represent a method of energy transfer through a medium or space by means of the regular vibration of particles (as in a sound wave) or a physical quantity, such as an elec- tromagnetic wave. An awareness of resonance is important in applications as diverse as communications and construction. Energy concepts are developed to encompass alternative forms.
