the time it takes for an object to complete a cycle of motion
period
number of cycles or vibrations per units of time
frequency
distance between any two repeating points on a wave
wavelength
distance from the equilibrium position to a crest or a trough
amplitude
highest point above equilibrium
crest
lowest point below the equilibrium
trough
require a medium to travel
mechanical waves
disturbance that transfer energy
waves
unit that wavelength is measured
meter
unit that wave speed is measured
meters per seconds
unit that frequency is measured in
hertz
energy moves through disturbance in the electromagnetic field
electromagnetic waves
what is another word for medium
matter
Greek letter that means wavelength
lambda
type of mechanical waves that makes a perpendicular line
transverse wave
type of mechanical wave that moves in a parallel direction
longitudinal wave
mechanical wave that propagates along the interface between differing media
surface wave
frequency of a mechanical wave is increased its wavelength must
decrease
speed of a wave will only change in a
new medium
line where the wave goes through
equilibrium
