Answer:Basic principles of Electromagnetic energy:wave definitions.these equations describe electromagnetic radiation as travelling at a velocity to 3×10 power8m/s in a sinusoidal, harmonic fashion.The electromagnetic wave is propogated in a direction perpendicular to the electric and magnetic fields.
Explanation:EM waves can trawl forever.Because they do not need a medium, EM waves can pass through outer space, which is a near vacuum.Also because they do not give up energy in traveling.
