Vibration: an oscillation of the parts of a fluid or an elastic solid whose equilibrium has been disturbed, or of an electromagnetic wave.
Wave: A wave is a disturbance that travels through a medium from one location to another location.
Wave Period: The period of a wave is the time for a particle on a medium to make one complete vibrational cycle. Period, being a time, is measured in units of time such as seconds, hours, days or years.
Crests: The highest part of a wave.
Troughs: a channel or conduit for conveying water, as a gutter under the eaves of a building for carrying away rain water.
Amplitude: the maximum extent of a vibration or oscillation, measured from the position of equilibrium.
Wavelength: the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
Frequency: the rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second.
Hertz: the SI unit of frequency, equal to one cycle per second._
Transverse Wave: A transverse wave is a moving wave that consists of oscillations occurring perpendicular to the direction of energy transfer.
