wave - A disturbance traveling through a medium where energy is transferred from one particle of the medium to another without causing any permanent displacement of the medium itself., frequency - he number of wavelengths that pass through a fixed point in one second; measured in Hertz, amplitude - measure of the size of the disturbance of a wave; height; half the full extent of a vibration, oscillation, or wave., crest - The part of a wave with greatest magnitude; the highest part of a wave., trough - The part of a wave with the least magnitude; the lowest part of a waveThe part of a wave with greatest magnitude; the highest part of a wave., transverse wave - a wave vibrating at right angles to the direction of its movement, longitudinal (compression) wave - A wave that is moving in the same direction as the displacement of the transmitting medium., reflection - a wave behavior in which waves strike an object and bounce back off, refraction - The turning or bending of a wave when it passes from one medium into another, interference - occurs when two waves meet while traveling along the same medium and combine to form a new wave, constructive interference - Occurs when waves add up to make a larger amplitude., destructive interference - Occurs when waves add up to make a smaller amplitude., medium - The substance or material that carries a wave, electromagnetic spectrum - The range of wavelengths or frequencies over which electromagnetic radiation extends, mechanical waves - A wave that is not able to transmit its energy through a vacuum; they require a medium in order to transmit energy., wavelength - The distance between one peak or crest of a wave and the next peak or crest., electromagnetic waves - A wave that is able to transmit its energy through a vacuum; they do not require a medium in order to transmit energy.,
