|
WAVES |
a repeating disturbance or movement that transfers energy through matter and transfers energy through it |
|
|
LONGITUDINAL WAVE |
a wave in which the matter in the medium moves back and forth in the same direction that the wave travels |
|
|
MEDIUM |
the matter through which a wave travels |
|
|
MECHANICAL WAVE |
waves that travel only through matter |
|
|
TRANSVERSE WAVE |
a wave in which matter in the medium moves back and forth at a right angle to the direction the wave travels |
|
|
AMPLITUDE |
the measure of the energy that a wave carries |
|
|
CREST |
the high point of a transverse wave |
|
|
COMPRESSION |
the more dense region of a longitudinal wave |
|
|
FREQUENCY |
the number of wave lengths that pass a fixed point in 1 second |
|
|
PERIOD |
the amount of time it takes one wavelength to pass a fixed point |
|
|
RAREFACTION |
the section in a compression wave where the material is less crowded and more spread out |
|
|
TROUGH |
the low point of a transverse wave |
|
|
WAVELENGTH |
the distance between one point on a wave and the nearest point just like it |
|
|
DIFFRACTION |
the bending of a wave around a barrier |
|
|
INTERFERENCE |
the point where two waves meet each other and overlap to form a new wave |
|
|
NODE |
location where interfering standing waves cancel |
|
|
REFRACTION |
the bending of a wave caused by a change in its speed as it moves from one medium to another |
|
|
RESONANCE |
the vibration of an object by absorbing energy from another object that is vibrating at its natural frequencies |
|
|
STANDING WAVES |
a wave pattern that forms when two equal-sized waves travel in opposite directions and interfere with each other |
