Term
Wavelength
Definition
The distance from crest to crest or trough to trough.
Term
Seismic Waves
Definition
A long-period wave caused by an underwater seismic disturbance or volcanic eruption.
Term
Amplitude
Definition
Half of the peak-to-trough range (or height) of a wave.
Term
Matter
Definition
Anything that has mass and occupies space.
Term
Rest
Definition
Not moving. At a stop point.
Term
Parallel
Definition
Be side by side with, always keeping the same distance.
Term
Perpendicular
Definition
A straight line at an angle of 90° to a given line, plane, or surface.
Term
Medium
Definition
Air, water, or solid (gas, liquid, solid).
Term
Compression
Definition
The action of compressing or being compressed.
Term
Frequency
Definition
The rate at which something occurs or is repeated over a particular period of time or in a given sample.
Term
Mechanical Wave
Definition
A mechanical wave is a disturbance that moves through a medium. The medium itself doesn't go anywhere. It's all energy with atoms and molecules.
Term
Rarefraction
Definition
When light rays break from a cubic crystal and they form different colours in straight lines.
Term
Vibration
Definition
An instance of vibrating.
Term
Energy Transfer
Definition
The transfer of energy of a given form among different scales of motion; for example, kinetic energy may be transferred between the zonal and meridional components of the wind, or between the mean and eddy components of the wind.
Term
Crest
Definition
The top of the wave or hill.
Term
Trough
Definition
The bottom of the wave or hill.
Term
Transverse Wave
Definition
A wave vibrating at right angles to the direction of its propagation.
Term
Energy
Definition
The capacity to do work. Work is done by transferring energy from one form to another.
Term
Longitudinal (compression) Wave
Definition
Longitudinal waves are waves that have the same direction of vibration along their direction of travel, which means that the vibration of the medium (particle) is in the same direction or opposite direction as the motion of the wave.
Term
Waves
Definition
A repeating disturbance or movement that
transfers energy through matter or space.
