The_Wave

The Wave THE WAVE A Wave is a periodic up-and-down movement of water. Wave Motion is where individual parts cycle up-and-down, or back-and-forth. It looks like something is actually moving, but in reality it's the distortion moving where one part makes the next part move. Distortion is a change in the shape of an image resulting from imperfections in an optical system, such as a lens. There are many different types of waves. Some that are involved in Wave Motion are as followed: Tranverse waves, Light waves, Compression waves, Sound waves, and Circular waves. An up-and-down motion creates Transverse waves. Light waves are caused by up-and- down motions of electric or magnetic fields, thus making them transverse waves. Back-and-Forth motion creates compression waves. A loudspeaker cone moves back-and-forth to create a sound wave. In cases where the material moves in a combination of transverse and compression ways, this creates circular waves.Characteristics that make up waves are it's: wavelength, amplitude, velocity, and frequency. Wavelength is the distance between wave crests. Amplitude is the height of the wave. Velocity is the measurement of how fast a crest is moving from a fixed point. Frequency describes the number of cycles that occur in a given time period.
