Molecule: the smallest particle of a substance
Compression: the 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 between one molecule in a body to the nearest molecule occupying a similar position and moving in the same direction.
Sound: a form of energy that is created when waves are created by certain kinds of vibrations
Crest: the highest point on a wave
Trough: the lowest point of a wave
Medium: a substance needed in order for a wave motion to be transmitted
Amplitude: the maximum distance a molecule has been moved from its normal position
Wavelength: the length of a wave
Frequency: the number of waves that pass a particular point in the body in a unit of time
velocity: the total distance traveled by a wave in a unit of time
vibration: the periodic motion of particles
vacuum: a completely empty space that does not contain any matter, not even air.
insulators: materials that are poor conductors of sound waves
intensity: the amount of energy passing through a unit area of a wave front in a unit of time
reflection: sound waves are reflected by a smooth surface
incident wave: the wave that strikes the reflecting wall
echo: when a sound is heard over and over again above the original sound
reverberation: the multiple refection of a single sound wave
absorption: the conversion of a part of the sound wave into heat
refraction:the bending of a wave as it passes through a medium
diffraction: the spreading of a sound wave around the opening of a barrier
