waves propagate by collision of particles, wave velocity is constant while particle velocity varies between a maxima n minima, does this mean dat d collisions are not elastic? if yes then wat happens do d stored potential energy?

Dear ekta,

Mechanical Waves are waves which propagate through a material medium (solid, liquid, or gas) at a wave speed which depends on the elastic and inertial properties of that medium. There are two basic types of wave motion for mechanical waves: longitudinal waves and transverse waves. The animations below demonstrate both types of wave and illustrate the difference between the motion of the wave and the motion of the particles in the medium through which the wave is travelling.
