wave periodic disturbance in a solid, liquid, or gas as energy is transmitted through a medium
longitudinal wave wave in which the particles of the medium vibrate parallel to the direction of wave motion
transverse wave wave in which the direction of displacement is perpendicular to the direction of propagation, as a surface wave of water
medium a material through which a wave can travel through
amplitude the maximum distance that the particles of a wave's medium vibrate from their rest position
wave speed the speed at which a wave travels through a medium
wave length the distance from any point on a wave to an identical pont on the next wave
frequency the number of waves produced in a given amount of time
reflection the bouncing back of a ray of light, sound, or heat when the ray hits a surface that it does not go through
refraction the bending of a wave as the wave passes between two substances in which the speed of the wave differs
diffraction a change in the direction of a wave when the wave finds an obstacle or an edge, such as an opening
interference the combination of two or more wave that results in a single wave
