WebNov 4, 2024 · An EM wave can travel without a material medium-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. Because they do not need a medium , EM waves can pass through outer space, which is a near vacuum. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space. In the 1860's and 1870's, a Scottish scientist named James Clerk Maxwell developed a scientific theory to explain electromagnetic waves. He noticed that electrical fields and … See more Electricity can be static, like the energy that can make your hair stand on end.
