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 |
