Propagation of an Electromagnetic Wave
Electromagnetic waves are waves that can travel by the vacuum of outer space. Mechanical waves, not like electromagnetic waves, need the presence of a material medium within order to transport their energy from one location to another. Sound waves are examples of mechanical waves although light waves are instance of electromagnetic waves.
