WebJul 31, 2024 · A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. The vacuum of space has very limited amounts of matter very spread out, therefore it's a very poor medium for wave propagation. WebIn a vacuum, electromagnetic waves travel at the speed of light, commonly denoted c. In homogeneous, isotropic media, the oscillations of the two fields are perpendicular to each other and perpendicular to the direction of energy and wave propagation, forming a transverse wave.
