refraction wave bends as it travels through different mediums
diffraction sound waves spread out after passing through an opening
reflection wave bounces off a surface at equal angles
longitudinal sound waves are
tranverse particles move up & down or perpendicular to direction of wave
crest top point of a transverse wave
trough bottom point of a transverse wave
amplitude distance from line of rest to top point of a transverse wave
wavelength distance from
echo reflection of sound wave off a surface
compression longitudinal wave section - waves close together
rarefaction Longitudinal wave section - waves spread apart
louder sound increased amplitude
softer sound decreased amplitude
light travels faster than sound
sound travels as a longitudinal wave
mechanical waves only travel through a medium - not in a vacuum(space)
refraction straw in a glass of water looks bent
speed of sound depends on medium sound is traveling through
gamma rays high frequency; short wavelength
radio waves low frequency; long wavelength
if frequency increases wavelength decreases
if frequency decrease wavelength increases
gases sound travels slowest through
solids sound travels fastest through
