Electromagnetic Waves Need A Medium To Travel Through

As discussed earlier, electromagnetic waves are unique in that they can travel through a vacuum, and all do so with the same speed (3 x 108 m/s). Other types of waves, such as sound waves, must travel through a medium such as air or water. Sound waves travel at varying speeds, for example at 343 m/s in dry air at room temperature and at ...

KEY CONCEPT Electromagnetic waves Have Unique Traits.
Medium and disappear. An EM wave can travel without any medium at all—that is, in a vacuum or space empty of matter—and does not lose energy as it moves. In theory, an EM wave can travel forever.

With the publication of "A Dynamical Theory of the Electromagnetic Field" in 1865, Maxwell demonstrated that electric and magnetic fields travel through space as waves moving at the speed of light. Maxwell proposed that light is an undulation in the same medium that is the cause of electric and magnetic phenomena. [7] ... Read Article
