thanseeq : The wave which donot require a medium for their propagation are called non mechanical wave, eg. light , heat , radio waves , they can travel in vaccum , all electro magnetic waves are non mechanical.
Meanical waves reqire a medium for propagation.in the propagation of mechanical waves elasticity and density of the medium plays an important role
