Waves and Energy, physical science

wave a disturbance that transfers energy from place to place
medium the material through which a wave travels
vibration a repeated back-and-forth or up-and-down in motion
mechanical wave waves that require a medium through which to travel ex: air, water, or a rope
transverse wave waves that move the medium at right angles to the direction which the waves travel
longitudinal wave move the medium parallel to the direction in which the waves travel
compression parts where the coils are close together
rarefaction the parts where the coils are spread apart
amplitude the maximum distance that the particles of the medium carrying the wave move away from the rest position
frequency the number of times a wave repeats
refraction the bending of waves due to a change in speed
diffraction when a wave moves around a barrier or through an opening in a barrier, it bends and spreads out
