Document Summary
Oscillations are localized in spaces but waves travel through space and time waves (cid:8869) Dole : - mechanical waves need a medium to propagate . Waves transport energy and momentum ( and information) but medium stays where it is . Waves are classified to transverse and long i tiedat. Solids can support both waves , but fluids only support longitudal waves. Asound wave is a longitudinal sound wave . wavelength. In transverse waves the medium is perpendicular to the direction of travel along the medium. Wave speed depends on properties of the medium. Periodic waves with s - m -m are called sinusoidal waves. When a sinusoidal ware passes though a median , every particle in the medium undergoes s . The wave advances by one wavelength 7 during each period t : wave motion us . particle motion. The ware moves with constant speed v along the length of the spring .
