vacuum a place with almost no matter, like space
tranverse wave goes in a direction that is perpendicular in which the wave is traveling
longitudinal wave goes in direction parellel to the direction in which the wave is traveling
amplitude the maximum distance the wave moves from its resting position
crest the tops of the waves
trophs the bottom of the waves
pitch describes how high or low a sound is
decibels units that sound is measured by
wave intensity the amount of energy the wave is carrying
wavelength the distance from one point on a wave to the same point on the next wave in the wave train
frequency (in a set of waves) how many waves pass by a specified point in a specified amount of time.
hertz stating cycles per second is call hertz
electromagnetic spectrum (ems) entire range of electromagnetic waves
the doppler effect the increase or decrease in the frequency of sound, light, or other waves
