Molecule: the smallest particle of a substance
compression: a close crowding together of molecules in some parts of a body
rarefaction: a spreading out of molecules in some parts of a body
wavelength: the distance from one crest to a consecutive crest or from a trough to the very next trough
frequency: the number of waves that pass through a body in a unit of time
period: the time required for a wave to travel a distance equal to its wavelength
velocity: total distance traveled by a wave in a unit of time
vibration: the periodic motion of particles. The primary source of sound
vacuum: a completely empty space that doesn't contain any matter including air
sound insulators: materials that do not conduct sound efficiently
diaphragm: a membrane similar to a drumhead
sine curve: the shape of a transverse wave
wave front: any curved surface passing through all the points of maximum compression at a uniform distance from the body
intensity: the amount of energy passing through a unit area of the wave front in a unit of time
amplitude: distance between line of origin and the crest of a wave
