STUDY
PLAY
echo
a repeated sound that occurs when sound waves bounce off a surface
pitch
the highness or lowness of a sound
reflection
the term for a light or sound wave that hits a surface and bounces off
conductors
materials that transfer heat easily
energy transformation
the change of energy from one form to another
vibration
to shake; back and forth motion
sound wave
a wave that transfers sound through matter
vacuum
empty space
wavelength
the distance from one area of crowded particles to the next
frequency
the number of vibrations a sound source makes in a given amount of time; how often something happens
amplitude
describes the standard diagram of a wave; wave's height
volume
