its the hieght of a wave
frequency
describes how close or far apart the waves are
is when sound bounces off hard objects
echo

how high or low a sound is
sound is produced when an object _________ back and fourth
viberates
the ______ of a sound is how loud or quiet the sound is
volume
sound is really just tiny __________ in the air
viberations
how much faster does sound travel through metal than through air
18 times faster
viberate
sound is produced when an object viberates back and fourth
volume
the volume of a sound is how loud or quiet the sound is
sound is a form of _______ that people can hear
energy
when the air particles bunch up and then spread out it creates a sound ______
wave
sound waves are _________ waves
longitudenal
the material that the sound wave moves through is called a
medium
without a medium sound cannot travel and so there is no sound in
outer space
the _______ of a sound wave is a measure of how many times an object viberates per second
frequency
objects that viberate with a high frequency produce sounds with high ______,
pitch
objects that viberate with a low frequency produce sounds with a ___ pitch
low
the _____ of a sound is how loud or quiet the sound is
volume
the more energy a sound has the ______ it will be
louder
waves that have a high _________ create a loud sound
amplitude
sometimes sound waves bounce off a hard, ______ surface producing an ______
smooth, echos
