wave
a periodic disturbance in a solid, liquid, or gas as energy is transmitted through a medium
medium
the physical thing though which a wave travels
transverse wave
a wave in which the particles of the medium move perpendicularly to the direction the wave is traveling
longitudinal wave
a wave in which the particles of the medium parallel to the direction of wave motion
amplitude
the maximum distance that the particles of a wave's medium vibrate from their rest position
wavelength
the distance from any point on a wave to an identical point on the next wave; typically measured crest to crest or trough to trough
wave speed
the speed at which a wave travels through a medium; sound waves travel fastest through solid and slowest through gasses
frequency
the number of waves produced in a given amount of time;
reflection
the bouncing back of a wave of light, sound, or heat when the wave hits a surface that it does not go through
perpendicular
intersecting at or forming right angles
parallel
extending in the same direction
rarefaction
The part of a longitudinal wave where the particles of the medium are far apart
compression
the part of a longitudinal wave where the particles of the medium are close together
