What property is common to all forms of electromagnetic radiation?

The main idea here is that all electromagnetic radiation propagates as energy carried by oscillating electric and magnetic fields that move through space. This propagation does not require a material medium; EM waves can travel in vacuum, all at the speed of light, and they carry energy and momentum without having rest mass. Because the electromagnetic spectrum spans a wide range of wavelengths—from radio waves to gamma rays—these waves do not share the same wavelength. So the property common to all forms is their ability to propagate energy through space (or matter), not requiring a medium, and without possessing rest mass.
