Parts of a Wave
This is a point of maximum positive displacement on a wave.
What is a wave crest?
This term is used to describe an ongoing series of disruptions in a wave.
What is a wave train?
This is the name that describes when a wave bounces off of a surface.
What is reflection?
The tendency of the frequency of a wave to seem higher or lower than the source frequency caused by relative motion between the source and detector.
What is doppler?
This is a point of maximum negative displacement on a wave.
What is a wave trough?
These kind of waves require collisions between particles of a medium in order to transport energy.
What are mechanical waves?
The phenomenon where the amplitudes of two overlapping waves add together with a resulting greater amplitude.
What is constructive interference.
A seemingly stationary wave caused by constructive and destructive interference of waves that match the resonance of an object.
What is a standing wave?
This is the distance between consecutive wave crests.
What is wavelength?
Particle motion is parallel to wave travel in these kinds of waves.
What are longitudinal waves?
The phenomenon where the amplitudes of two overlapping waves subtract from each other with a resulting lower amplitude.
What is destructive interference?
Applying additional energy or force at the proper time and frequency to either maintain or increase a wave's amplitude.
What is forced resonance?
This is the time it takes for a wave to complete a single cycle.
What is the period?
What are transverse waves?
The phenomenon where light changes direction as it enters a different medium.
What is refraction?
This is what happens when an opposing force causes the amplitude of periodic motion to decrease.
What is damping?
This is the number wave cycles completed in a unit of time. Also, the inverse of the period.
What is the frequency?
It is disruptions to this that allow some waves to travel without the use of a medium.
What is the electromagnetic field?
The phenomenon where a wave will bend around an object.
What is diffraction?
When the frequency of forced oscillations match the natural frequency of an object, resulting in high amplitude waves.
What is resonance?
