The description and analysis of wave propagation phenomena provides a unifying thread connecting diverse areas. The nature of waves summary the physics hypertextbook. In physics a wave can be thought of as a disturbance or oscillation that travels through spacetime, accompanied by a transfer of energy. Electromagnetic waves include, radio waves, microwaves, infrared, light, ultraviolet, xrays, and gamma rays. How can it make sense to use the same word wave for all these disparate phenomena. Motion of the waves energy motion of individual molecules of the wave transverse waves two motions are perpendicular waves on a string, water surface waves longitudinal waves two motions are parallel sound waves waves can have both transverse and longitudinal motion. Wave motionis the disturbance, set up in the medium, due to the repeated periodic motion of the particles of the medium and travels from the particle to particle, the particles themselves keep vibrating about their mean positions.

Stationary or standing waves have become very important in physics in the last hundred years or so. I hope to emphasize that the physics of standing waves is the same. I have a go at recreating this effect myself and also show you some of the equations and why this effect is important in physics.
Traveling waves appear only after a thorough exploration of onedimensional standing waves. Even more important, though only touched on in this book, is the wave phenomenon of quantum mechanics, built into the fabric of our space and time. Transverse waves vibrations are perpendicular to the wave motion so if the wave is travelling horizontally, the vibrations will be up and down. Wave motion is classified into three different ways they are, the medium of propagation, the dimensions in which a wave propagates energy, the energy transfer.
