 wave speed the speed at which a wave travels wavelength the distance between one point on a wave and the corresponding point on an adjacent wave in a series of waves wave a disturbance that transmits energy through matter or space trough the lowest point of a transverse wave transverse wave a wave in which the particles of the wave’s medium vibrate perpendicular to the direction the wave is traveling surface wave a wave that occurs at or near the boundary of two media and that is a combination of transverse and longitudinal waves standing wave a wave that forms a stationary pattern in which portions of the wave do not move and other portions move with a large amplitude resonant frequencies the frequencies at which standing waves are made resonance what occurs when an object vibrating at or near a resonant frequency of a second object causes the second object to vibrate refraction the bending of a wave as it passes at an angle from one medium to another reflection the bouncing back of a wave after it strikes a barrier or an object rarefaction a region of lower density or pressure in a wave perpendicular at right angles medium a substance through which a wave can travel longitudinal wave a wave in which the particles of the medium vibrate back and forth along the path that the wave travels interference a wave interaction that occurs when two or more waves overlap hertz (Hz) the unit used to express frequency; one hertz is one cycle per second frequency the number of waves produced in a given amount of time electromagnetic wave a wave that can travel through space or matter and consists of changing electric and magnetic fields echo a reflected sound wave diffraction the bending of waves around a barrier or through an opening destructive interference interference that results in a wave that has a smaller amplitude than that of the individual waves crest the highest point of a transverse wave constructive interference interference that results in a wave that has a greater amplitude than that of the individual waves compression a region of higher density or pressure in a wave amplitude the maximum distance a wave vibrates from its rest position
