Term | Definition |
---|---|
transverse wave parts | crest trough amplitude wavelength |
longitudinal wave parts | rarefaction compression wavelength |
amplitude | from normal to crest or trough |
wavelength | crest to trough |
frequency | the number of waves that pass by a place at a certain time |
refraction | the bending of a wave because of different media |
reflection | a wave hits a surface and bounces off |
diffraction | the bending of a wave as it touches the edge |
constructive | results in a larger wave |
destructive | results in a smaller wave |
period | time it takes to complete one cycle |
transverse where | propagates energy perpendicular to the wave |
longitudinal where | propagates energy parallel to the wave |
sonic boom | compressions pile up since the source is traveling faster than sound |
vibrations | source of all sounds |
