wave a periodic disturbance in a solid, liquid, or gas as energy is transmitted through a medium
medium a physical environment in which phenomena occur
mechanical wave a wave that needs a medium in which to travel
transverse wave a wave in which the particles of the medium move perpendicularly to the direction the wave is traveling
longitudinal wave a wave in which the particles of the medium vibrate parallel to the direction of wave motion
compression par of the longitudinal wave in which the particles expand and move apart
rarefraction part of the longitudinal wave in which the particles expand and move apart
electromagnetic wave a wave that consists of electric and magnetic fields that vibrate at right angles to each other
reflection the bouncing back of a ray of light, sound, or heat when the ray hits a surface that does not go through
refraction the bending of a wave as the wave passes between the 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
transmission the passing of light of other form of energy through matter
