1WaveA disturbance that transfers
energy from place to place
2EnergyThe ability to do work
3MediumThe material through which
a wave travels
4Mechanical waveA wave that requires a medium
through which to travel
5VibrationA repeted back and forth
or up and down motion
6Transverse waveA wave that moves across in one direction
7Longitudinal waveThe particles of the medium move
parallel to the direction
that the wave is travelling
8surface wavesOccur at the surface between 2
mediums; particles
move in a circular motion;
combinations of transverse
and longitudinal waves
9AmplitudeThe maximum distance the medium
carrying the wave moves away
from rest position; how big the wave is
10Longitudinal waveslook at the compression; the greater
the compression, the louder the sound
11wave lengththe distance between 2 corresponding
parts of a wave
12frequencythe number of complete waves that pass a given point in a certain amount of time
13hertzwhat frequency is measured in
14speedhow far a wave travels in one unit of time
15rateDistance/time
16Common units of measurementmph,
km/h,
km/sec
17reflectionwhen an object or wave hits a surface through which it cannot pass, it bounces back
18refractionwhen a wave moves from one medium into another medium at an angle, it changes speed in the second medium, which causes it to bend.
