– They transport both energy and momentum.
– Being transverse waves, they can be polarized. They also undergo reflection, refraction, diffraction, and interference.
– The statement that electromagnetic wave propagation is described by varying electric and magnetic fields is fundamental to Maxwell’s equations, which govern their behaviour.
