The part of a longitudinal wave where the particles are pushed together.
When sound appears to change frequency as it moves past a listener.
Something that a wave travels through.
The rate at which work is done. This is equal to the amount of energy being produced.
A part of a longitudinal wave where the particles are spread apart
The increase in the amplitude of a wave when it comes into contact with external vibrations that match the object's natural frequency.
The lowest part of a wave
The maximum distance a point is moved from the rest position
The highest part of a wave
The number of waves that pass a point each second.
Repeated back-and-forth or up-and-down motion
Distance between two neighboring corresponding points on a wave (two crests, two troughs, etc)
The distance a wave travels in a given amount of time.
The distance moved up or down as the wave passes through
The distance moved left or right as the wave passes through
Match the definition to the vocabulary word.
A disturbance that transfers sound energy from place to place.
A wave that moves through a medium in the same direction (parallel) to the wave (appears to move from left to right)
A wave in which the motion of the medium is perpendicular to the direction of the wave (Usually shown on graphs in an up/down movement)
A wave that requires a medium to move through
