We can distinguish between two classes of waves, based on the motion of the medium through which it propagates. With transverse waves, the elements of the medium oscillate back and forth in a direction perpendicular to the motion of the wave.

A wave is a disturbance in a medium that carries energy without a net movement of particles. It may take the form of elastic deformation, a variation of pressure, electric or magnetic intensity, electric potential, or temperature. Table of Content. Introduction of Waves. Types of Waves.
21 Οκτ 2024 · wave, propagation of disturbances from place to place in a regular and organized way. Most familiar are surface waves that travel on water, but sound, light, and the motion of subatomic particles all exhibit wavelike properties.
Key points: A wave is a repeating disturbance that travels through matter or space transferring only energy. Below is a model of a wave. A wave’s crest is its highest point, and its trough is its lowest point. A wave’s amplitude is the maximum distance (positive or negative) a wave reaches from its rest position.
Waves transfer energy, momentum, and information, but not mass. A naive description of a wave is that it has something to do with motion. But the motion of a wave on the water is not the same as the motion of the water from a hose. When waves move over the surface of the ocean, where does the ocean go? Nowhere.
In physics, mathematics, engineering, and related fields, a wave is a propagating dynamic disturbance (change from equilibrium) of one or more quantities. Periodic waves oscillate repeatedly about an equilibrium (resting) value at some frequency.
Visualizing water waves is useful because there is more to it than just a mental image. Water waves exhibit characteristics common to all waves, such as amplitude, period, frequency and energy. All wave characteristics can be described by a small set of underlying principles.
