sound waves
longitudinal waves that can only travel through matter
longitudinal wave
a wave that makes the particles in the material that carries the wave move back and forth along the direction the wave travels
vibration
is a rapid back and forth motion that can occur in solids liquids or gases
medium
a material in which a wave travels through
compression
a region of a longitudinal wave where the particles in the medium are closest together
rarefaction
a region of a longitudinal wave where particles are farthest apart
amplitude
for a longitudinal wave the maximum distance the articles in a medium move from their rest positions as the wave passes through the medium
intensity
the amount of sound energy that passes through a square meter of space in one second
wavelength
the distance between a point on one wave and the nearest point just like it
frequency
the number of wavelengths that pass a point each second
picth
how high or low a sound is
Doppler effect
the change of pitch when a sound source s moving in relation to an observer
interference
occurs when wave that overlap combine forming a new wave
resonance
an increase in amplitude that occurs when an object vibrating at its natural frequency absorbs energy from a near by object vibrating at the same frequency
absorption
the transfer of energy by a wave to the medium through which it travels
reflection
the bouncing of a wave off a surface
echo
reflected sound wave
reverberation
the collection of reflected sound from the surface in a closed space
acoustics
the study of how sound interacts with structures
echolocation
the process an animal uses to locate an object by reflected sounds
sonar
a system ghat uses the reflection of sound waves to find underwater objects
