Waves
defenitions based on Waves unit
Term | Definition |
---|---|
Wave | a repeating disturbance or movement that transfers energy through matter or space |
Medium | the matter that waves travel through |
Transverse | matter in the medium moves back and forth at right angles to the direction that the wave travels |
Compressional Wave | matter moves back and forth along the same direction that the wave travels, have a rarefaction and compression |
Seismic Waves | when earths crust shifts or bends, the breaking crust vibrates carrying energy outward |
Crests | high points of a wave |
Trough | low points of a wave |
Rarefaction | less dense region of the wave |
Amplitude | the height of the wave |
Frequency | the number of wavelengths that pass a fixed point each second |
Period | the amount of time it takes one wavelength to pass a point |
Wave Speed | wave speed=frequency(HZ) * wavelength(m) v=f*/\ |
