Electromagnetic Waves are wavy electric and magnetic fields that travel through space. these are radio waves, microwaves, infrared, visible light, ultraviolet, X-rays and gamma rays. They travel in vacuum at the speed of light & require no medium. They exhibit wave/particle duality, polarization and can be transmitted, refracted, diffracted and absorbed.
