Properties Of Sound Waves
a rapid back-and-forth movement
What is a vibration?
the distance from one compression to the next
What is a wavelength?
the part of the wave where the motion of the vibration spreads apart
What is a rarefaction?
how high or low of a given sound
What is pitch?
a sound wave that bounces back towards its source
What is an echo?
a vibration that can be heard
What is a sound?
the number of waves that pass a point in one second
What is frequency?
What is air?
how loud or soft a sound is
What is volume?
the type of surface that produces a clear echo
What is a smooth surface?
a disturbance that moves energy from place to place
What is a wave?
instrument used to help us "see" pictures of sound waves
used to make the changes in the volume of sound
What is the amount of energy?
how the intensity of sound is measured
What are decibels?
the two factors that affect the clarity of an echo
What is the distance and the type of surface?
the kind of waves that can move only through matter
What is mechanical waves?
the unit used to measure frequency
What is the hertz?
the quality of sound that distinguishes it from other sounds with the same quality and pitch
What is timbre?
the quality of sound that distinguishes it from other sounds
What is timbre?
the ability to see with sound
What is echolocation?
the part of a sound wave where the vibration pushes together some of the particles of matter

What are rough, soft, or fuzzy materials?
three characteristics of sound
pitch, volume, and quality
