Waves

TermDefinition
energy the amount of ability in something to do work.
wave a disturbance that transfers energy from one place to another.
medium any substance that a wave moves through.
wavelength transverse - the distance from one wave crest to the very next crest. Longitudinal - how compressed the medium gets.
crest the highest point of a wave.
trough the lowest point of a wave.
frequency number of waves passing a fixed point in a certain amount of time, measured in Hertz - one hertz is one wavelength per second. As frequency increases, wavelength decreases.
amplitude the bigger the amplitude, the more energy the wave has.
transverse wave the direction the wave moves is perpendicular to the direction of the disturbance. Ex. Light waves.
longitudinal wave the wave travels in the same direction as the disturbance. Ex. sound waves.
compression where matter is bunched together.
equilibrium the original state/place of matter.
claim the main reason or point of a statement.
evidence supporting facts or information to a main point.
