intensity?
the amount of sound energy that passes through a square meter of space in one second
wavelength?
the distance between a point on one wave and the nearest point
frequency?
the number if wavelengths that pass by a point each second
pitch?
the perception of how high or low a sound seems
doppler effect
the change of pitch when a sound source is moving in relation to an observer
interference
when waves that overlap combine, forming a new wave.
resonance?
an increase in amplitude that occurs when an object vibrating at its natural frequency absorbs energy from a nearby object vibrating at the same frequency
constructive interference?
when the compressions and rarefactions of waves overlap
destructive interference?
when the compressions of one wave overlap the rarefactions of another wave.
beats?
when the compressions of two waves are slightly offset

Amplitude?
the maximum distance the particles in a medium move from their rest positions as the wave passes through the medium
