medium		lowest point of a wave
frequency		when an object causes a wave to change direction
soundwave		another name for a longitudinal wave
transverse		light that bounces back from an object
amplitude		example of a transverse wave
rarefaction		bending of light waves
trough		key word for this is tuning fork
polarized		measure of energy a wave carries
wave		___________ frequency = shorter wavelength
oceanwave		distance from any part of one wave to its corresponding point on the next wave
longer		this wave moves in a snakelike fashion
reflection		these waves can travel through empty space
higher		matter that carries a wave
wavelength		____________ waves are vibrations that move back and forth in one plane
velocity		disturbance that carries energy
diffraction		part of the wave where particles are far apart
refraction		lower frequency = __________ wavelength
electromagnetic		example of a longitudinal wave
resonance		highest point of a wave
crest		____________ of a wave = frequency x wavelength
compression		number of wavelengths that pass by a point in space each second
