|
wave |
repeating disturbance or movement that transfers energy through matter or space |
|
|
medium |
the matter the waves travel through |
|
|
transverse wave |
matter in the medium moves back and forth at right angles to the direction that the wave travels |
|
|
compressional wave |
matter in the medium moves back and forth along the same direction that the wave travels |
|
|
crest |
transverse wave that has alternating high points |
|
|
trough |
low points of a transverse wave |
|
|
rarefaction |
less-dense region of a compressional wave |
|
|
wavelength |
the distance between one point on a wave and the nearest point just like it |
|
|
frequency |
# of a wave lengths that pass a fixed point second |
|
|
period |
amount of time it takes one wave length to pass a point |
|
|
amplitude |
related to the energy carried by a wave |
|
|
refraction |
bending of a wave caused by a change in its speed |
|
|
diffraction |
occurs when an object cause a wave to move direction and bend around it |
|
|
interference |
when 2 or more waves overlap. |
|
|
resonance |
an object is made to vibrate |
|
|
standing wave |
wave pattern that forms when waves equal in wavelength |
