Waves
Term | Definition |
---|---|
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 |
