12 Μαρ 2024 · Table of contents. Figure 5.1.1 5.1. 1: There are at least four types of waves in this picture—only the water waves are evident. There are also sound waves, light waves, and waves on the guitar strings. (credit: John Norton)
An oscillation is a back and forth motion of an object between two points of deformation. An oscillation may create a wave, which is a disturbance that propagates from where it was created. The simplest type of oscillations and waves are related to systems that can be described by Hooke’s law.
The movement of the energy through the oscillating material is what we call a 'wave'. Waves can move from one medium to the next, like when an earthquake causes ripples in a swimming pool. Waves can reflect off an interface between two different mediums, like when light moves from the air to water and reflects off the water surface.
Given a disturbance from its usual resting or equilibrium position, an object begins to oscillate back and forth. In this Lesson, the concepts of a disturbance, a restoring force, and damping are discussed to explain the nature of a vibrating object.
Learn about the properties and applications of these rhythmic movements, including simple harmonic motion, pendulums, and waves. Explore the key concepts and equations behind oscillations and their relevance to real-world phenomena.
16 Ιουλ 2018 · Here we’ll discuss oscillations in which the position graph of the oscillating object is a sine or cosine wave; this is simple harmonic motion (SHM). Also characteristic of SHM is repeated transformation of potential energy to kinetic, then of kinetic to potential.
