Explanation:

Electromagnetic (E.M.) waves are form of energy which do not require any physical medium for propagation or EM waves can travel through the vacuum because EM waves consist of electric & magnetic field vectors oscillating in mutually perpendicular directions which are perpendicular to the direction of propagation. EM waves travel at the speed of light i.e. #3\times 10^8\ \text{m/s}#
