The Wave

            
             A Wave is a periodic up-and-down movement of water.
             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. .
             Some formulas are Frequency = Velocity/Wavelength or Velocity = .
             Wavelength X Frequency. Frequency is measured in hertz. This shows the .
             relationship between frequency, wavelength, and velocity. When waves.
             move through material, they're velocity usually changes. When a wave .
             meets up with an abstacle, it is transmitted, reflected, and absorbed. .
             When a wave meets the edge of an abstacle, diffraction occurs when .
             it bends slightly. Diffraction is a change in directions and intensities of a .
             group of waves after passing by an abstacle or through an aperture .
             whose size is approximately the same as the wavelength of the waves. .
             Waves-ripples, ridges, and hollows moving over the water are the cause.
