Answer: The correct answer is electromagnetic wave.
Explanation:
Electromagnetic wave is wave in which the electric field and the magnetic field are perpendicular to each other. Both fields are directed to the direction of the propagation of the wave.
Electromagnetic wave is transverse in nature. It travels with the speed of the light. It does not need medium to travel. It can be transmitted through the vacuum of space.
Therefore, the correct answer is electromagnetic wave.
