WebAlthough conceived of as distinct phenomena until the 19th century, electricity and magnetism are now known to be components of the unified field of electromagnetism. Particles with electric charge interact by an electric force, while charged particles in motion produce and respond to magnetic forces as well. WebJul 23, 2024 · The simplest phenomenon was the transmission of light in straight lines, as in shafts of sunlight through a cloud or solar eclipses. Such behaviour was expected for a stream of corpuscles, but not for a wave. Water waves rippling from a stone dropped into a pond could be seen to spread in all directions and bend around obstacles to some extent.
