wave		Movement that follows the same path over and over again
vibrations		Bending of waves due to a change in speed
medium		Interaction of waves that occur at the same place at the same time
mechanical wave		Wave that consists of a combination of transverse and longitudinal waves and occurs at the surface between two different mediums
electromagnetic wave		Distance between two consecutive similar points on a wave
crest		Wave that consists of electric and magnetic fields and does not require a medium to exist
trough		High point of a wave
amplitude		Wave in which the motion of the medium is parallel to the direction of the wave
wavelength		Traveling disturbance that carries energy from one place to another
frequency		Bouncing back of waves uon reaching another surface
transverse wave		Number of wves that pass a certain point in a given amount of time
longitude wave		Greatest distance from rest to crest of a wave
surface wave		Wave in which the motion of the medium is at right angles to the direction of the wave
reflection		Frequency at which a standing wave occurs
refraction		Wave that does not appear to be moving, occurs at the natural frequency of the material
diffrction		Low point of a wave
interference		Wave that disturbs a medium
standing wave		Bending of waves around the edge of an object
resonant frequency		Material through which a mechanical wave travels
