Description about eBook : INTRODUCTION
When a stone is dropped into water, its surface gets disturbed. A disturbance is produced at the point where the stone enters into water. This disturbance does not confine to that place along where stone is dropped but it spreads out. The disturbance spreads in the form of the concentric circles of ever-increasing radii eventually reach all the parts and strike the boundary of the pond. Now let us put a wooden block on the disturbed water surface. The wooden block moves up and down as the ripples pass but does not move outward along with the ripples. This clearly indicates that the particles of water do not move outward with the disturbance. Up and down motion of wooden block as the wave disturbance passes on the water surface. Thus a disturbance which communicated from one to another place without transfer of medium is called wave motion. Such a wave which require material medium for its propagation is called mechanical wave. The wave which requires no material medium for its propagation is called electromagnetic wave. Remember that mechanical wave can travel only in a medium which has elasticity. Properties of medium require for wave motion If a wave is to travel through a medium such as water, air, string, it must cause the particles of medium to oscillate as it passes through the medium. For this to happen, the medium must have inertia so that kinetic energy can be stored. Then, the particles can overshoot their mean position. After being displaced, the particles tend to regain the original position. For this the medium must store potential energy, which require elasticity to do this. Thus for the propagation of wave, medium must have inertia and elasticity . These two properties of medium decides the speed of the wave.............
