Bill
repeating disturbance that transfers energy from one place to another
wave
volume empty of matter, sometimes called “free-space”
vacuum
the lowest point or valley of a transverse wave, representing maximum negative displacement
trough
the matter that a wave travels through (ex: ocean wave’s medium is
medium
measure of how far apart a particle in the medium moves away from its normal rest position
amplitude
distance from any point on the wave to an identical point on the next wave pulse
wavelength
waves that transfer energy through a medium
mechanical wave
the highest point or peak of a transverse wave, representing maximum positive displacement
crest
number of waves produced in a set amount of time, usually measured in hertz (Hz). One hertz equals one wave per second
frequency
particles vibrate perpendicularly to the direction the wave travels
transverse wave
region in a longitudinal wave where the particles are closest together (more dense)
compression
the rate at which a wave travels.
wave speed
particles vibrate parallel to the direction the wave travels
longitudinal wave
region in a longitudinal wave where the particles are the farthest part (less dense)
rarefaction
v = 𝛌ᐧf
formula for wave speed
