type of wave that requires matter to transfer energy
mechanical
type of wave that does not require a medium to transfer energy
electromagnetic
type of mechanical wave where matter is moved back and forth at right angles to the waves
transverse
type of mechanical wave where particles of matter move in the same direction as the wave
compression
direction of a wave measured from top or bottom of the midline
amplitude
the highest point of the wave
crest
the lowest point of the wave
trough
the midline of the wave
restposition
measurement from crest to crest
wavelength
number of wavelengths that pass a given point in a second
frequency
where light or sound waves bounce off a surface
reflection
bending of a wave as it passes from one medium to another
refraction
bending of a wave
diffraction
light is taken in and temperature increases
absorption
light passing through a medium with no interruptions
transmission
communication signal where the wave is continuous
analog
signal that uses binary code and has a uniform structure
digital
code used in digital signals that allows for precise messages
binary
