the bending of waves around a barrier or through an opening
diffraction
when an object vibrating at or near the resonant frequency of a second object causes the second object to vibrate
resonance
the highest point of a transverse wave
crest
a wave in which the particles of the medium vibrate parallel to the direction of wave motion
longitudinal
the bending of a wave as the wave passes from one medium to another at an angle
refraction
any disturbance that transmits energy through matter or empty space
wave
part of a longitudinal wave where the particles are crowded together
compression
the way frequency is usually expressed
hertz
the speed at which a wave travels through a medium
wavespeed
the combination of a transverse wave and longitudinal wave
surfacewave
a pattern of vibration that simulates a wave that is standing still
standing
result of two or more waves overlapping
interference
when a wave bounces back after hitting a barrier
reflection
the distance between any two crests or compressions next to each other in a wave
wavelength
a wave that can transfer energy without a medium
electromagnetic
a wave in which the particles vibrate up and down
transverse
a physical environment in which phenomena occur
medium
the lowest point between each crest
trough
the number of waves produced in a given amount of time
frequency
the maximum distance that the particles of a wave's medium vibrate from their rest position
amplitude
