|
wave
|
disturbance that transmits energy
|
|
|
transverse wave
|
wave that causes the particles of the medium to vibrate perpendicularly to the direction the wave travels
|
|
|
constructive interference
|
any intreference in which waves combine so that the resulting wave is bigger than the original waves
|
|
|
reflection
|
bouncing back of a wave when the source or observer is moving
|
|
|
crest
|
highest point of a transverse wave
|
|
|
diffraction
|
bending of a wave as it passes an edge or an opening
|
|
|
trough

lowest point of a transverse wave
|
|
|
amplitude
|
greatest distance that particles in a medium move from their normal position when a wave passes
|
|
|
electromagnetic wave
|
a wave caused by a disturbance in electric and magnetic fields that does not require a medium
|
|
|
doppler effect
|
observed changed in the frequncy of a wave when the source or observer is moving
|
|
|
mechanical wave
|
wave that requires a medium through which to travel
|
|
|
wave speed
|
speed at which a wave passes through a medium
|
|
|
longitudinal wave
|
wave that causes the particles of the medium to vibrate parallel to the direction the wave travels
|
|
|
destructive interference
|
any interference in which waves combine so that the resulting wave is smaller than the largest of the original waves
|
|
|
medium
|
the matter through which a wave travels
|
|
|
interference
|
combination of two or more waves that exist in the same place at the same time
|
|
|
wavelength
|
distance between any two successive identical parts of a wave
|
|
|
frequency
|
number of vibrations that occur n a 1 second time interval
|
|
|
period
|
full time required for one full wavelength to pass a certain point
|
|
|
refraction
|
bending of waves as they pass from one medium to another
|
|
|
standing wave
|
a wave caused by interference that appears not to move along the medium and that shows some regions of maximum vibration (antinodes)
