|
longitudinal ( compression ) wave |
a wave in which the vibration of the medium is parallel to the direction the wave travels |
|
|
amplitude |
the maximum displacement of a medium from the rest position |
|
|
rarefaction |
an area if longitudinal wave where the particles of the medium are spread out |
|
|
compression |
an area of longitudinal wave where the particles of the medium are close together |
|
|
period |
the time required for one complete cycle of a periodic motion |
|
|
frequency |
the number if complete cycles per unit time for periodic motion |
|
|
wave velocity |
the rate at which a wave travels through a medium |
|
|
wavelenght |
the distance between a point on a wave and the same point on the next cycle of the wave |
|
|
transverse wave |
a wave that causes a medium to vibrate at right angles to the direction in which the wave travels |
|
|
mechanical wave |
a disturbane in matter that carries energy from one place to another |
|
|
electromagnetic wave |
a transverse wave consisting of changing electric and changing magnetic fields |
|
|
surface wave |
a wave that travels along a surface scanarating two media |
|
|
medium |
the material through which a wave travels |
|
|
reflection |
the interaction that occurs when a wave bounces off a surface rear it cannot pass through |
|
|
refraction |
the bending if a wave as it enters a new medium at an angle |
|
|
wave interference |
the variation of wave amplitude that occurs when waves of the same or nearly the dame frequency come together |
|
|
constructive interference |
the interference among two or more waves in which displacements combine to produce a wave with a larger displacement |
|
|
destructive interference |
the interation among to or more waves in which displacements to produce a wave with a smaller displacements |
|
|
diffraction interference |
the bending of a wave as it moves around an obstacle or passes through a narrows opening |
