What is the maximum amount of displacement of a particle on the medium from its rest position.
100
Rarefaction
What is a point on a medium through which a longitudinal wave is traveling that has the minimum density.
100
Refraction
What is a change in the direction of waves as they pass from one medium to another.
100
Diffraction
What is a change in direction of waves as they pass through an opening or around a barrier in their path.
200
Reflection
What is waves will always reflect in such a way that the angle at which they approach the barrier equals the angle at which they reflect off the barrier.
200
Crest
What is the top of the wave
200
Longitudinal Wave
What is a wave in which the particles of the medium are displaced in a direction parallel to the direction of energy transport.
200
Constructive Interference
What is the type of interference occurs when two interfering waves have a displacement in the same direction.
200
Resting point
What is the spot where the wave begins disturbing the medium
300
Node
What is a points, sometimes described as points of no displacement, are referred to as
300
Transverse Wave
What is a wave in which the particles of the medium are displaced in a direction perpendicular to the direction of energy transport.
300
Frequency
What refers to how often the particles of the medium vibrate when a wave passes through the medium.
300
Destructive Interference
What is a type of interference occurs when two interfering waves have a displacement in the opposite direction.
300
Compression
What is a force is applied, and the energy is transferred in the same direction causing the compression of the medium.
400
Antinode
What are the opposite of nodes, and so they are called

Standing Wave
What is a wave pattern that is characterized by points that appear to be standing still?
400
Period
What is the time for a particle on a medium to make one complete vibrational cycle.
400
Medium
What is a substance or material that carries the wave.
400

500
Wavelength
What is simply the length of one complete wave cycle.
