Wave
|
a repeating disturbance or movement that transfers energy through matter or space.
|
|
Medium
|
the matter the waves travel through.
|
|
Transverse Wave
|
a type of wave, such as a water wave, where the matter in the medium moves back and forth at right angles to the dirrection that the wave travels; has crests and troughs.
|
|
Compressional Wave
|
a type of wave were the matter in the medium moves back and forth in the same dirrection that the wave traces; has compression and rarefaction.
|
|
Crest
|
the highest point of a transverse wave.
|
|
Trough
|
the lowest point of a transverse wave.
|
|
rarefaction
|
the less-dense region of a compressionalwave.
|
|
Wavelength
|
the distance between one point on a wave and the nearest point just like it.
|
|
Frequency
|
measures how many wavelengths pass a fixed point each second and expressed in hertz.
|
|
Amplitude
|
a measure of the energy carried by a wave.
|
|
Refraction
|
the bending of a wave caused by a change in its speed as it moves from one medium to another.
|
|
Diffraction
|
occurs when an object causes a wave to change dirrection and bend around it.
|
|
Interference
|
occues when two or more waves overlap and combine to form a new wave; can form a larger wave (constructive interfearance) or a smaller wave (destructive wave)
|
|
Standing Wave
|
a special type of wave pattern that forms when wave equal in wavelength and amplitude, but traveling in oposite direction, continues to interfear with eachother.
|
|
Resonance
|
the ability of an object to vibrate by absorbing engery at its natural frequency.
