Sound

TermDefinition
sound is a disturbance that travels through a medium as a longitudinal wave
sound waves like other mechanical waves, carry energy through a medium without moving the particles of the medium along
air is a common medium for sound
solids and liquids sound can travel through these too
sound waves reflect off objects
sound waves diffract through narrow openings, and around barriers
sound waves interfere with each other
echo is what a reflected sound wave is called
interference occurs when sound waves meet, and it can be constructive and destructive
the speed of sound depends on the elasticity, density, and temperature of the medium the sound travels through
elasticity is the ability of a material to bounce back after being disturbed
the elasticity of a medium depends on how well the medium's particles bounce back after being disturbed
the more elastic a medium the faster sound travels in it
density is how much matter, or mass, there is in a given amount of space, or volume
