26 Cards in this Set

  • Front
  • Back
wave speed
the speed at which a wave travels
wavelength
the distance between one point on a wave and the corresponding
point on an adjacent wave in a series of waves
wave
a disturbance that transmits energy through matter or space
trough
the lowest point of a transverse wave
transverse wave
a wave in which the particles of the wave’s medium vibrate
perpendicular to the direction the wave is traveling
surface wave
a wave that occurs at or near the boundary of two media and that
is a combination of transverse and longitudinal waves
standing wave
a wave that forms a stationary pattern in which portions of the
wave do not move and other portions move with a large amplitude
resonant frequencies
the frequencies at which standing waves are made
resonance
what occurs when an object vibrating at or near a resonant frequency
of a second object causes the second object to vibrate
refraction
the bending of a wave as it passes at an angle from one medium to
another
reflection
the bouncing back of a wave after it strikes a barrier or an object
rarefaction
a region of lower density or pressure in a
wave
perpendicular
at right angles
medium
a substance through which a wave can travel
longitudinal wave
a wave in which the particles of the medium vibrate back
and forth along the path that the wave travels
interference
a wave interaction that occurs when two or more waves overlap
hertz (Hz)
the unit used to express frequency; one hertz is one cycle per second
frequency
the number of waves produced in a given amount of time
electromagnetic wave
a wave that can travel through space or matter and
consists of changing electric and magnetic fields
echo
a reflected sound wave
diffraction
the bending of waves around a barrier or through an opening
destructive interference
interference that results in a wave that has a smaller
amplitude than that of the individual waves
crest
the highest point of a transverse wave
constructive interference
interference that results in a wave that has a greater
amplitude than that of the individual waves
compression
a region of higher density or pressure in a wave
amplitude
the maximum distance a wave vibrates from its rest position
