The speed of a wave can be found by the medium properties through which it travels. For mechanical waves, the speed of the wave depends on the inertia and elasticity of the medium. For example, the speed of a wave is dependent on the mass of the wave per unit length and the tension in the string.
Also, sound travels in solids at a greater speed than in liquids and gases because, in a solid, the particles are more tightly packed. In the case of electromagnetic waves, the speed of waves is the highest in vacuum and it depends on the magnetic and electric properties of the medium. The type of wave also matters which can be longitudin...more
