In my intro to E&M course, in the section on electromagnetic waves, my textbook just says that electric and magnetic waves are orthogonal to each other, but it doesn't say why. How do we know this? Is it from solving the wave partial differential equation? If so, given that I've tooken a course on intro to DEs that slightly covered PDEs, is it possible for me to solve the wave equation and find out the the E and M waves are orthogonal to each other?(adsbygoogle = window.adsbygoogle || []).push({});
