Answer:
No.
Electromagnetic waves do not need a medium to travel through.
Step-by-step explanation:
Wave: A wave is a disturbance which travel through a medium and transfer energy from one point to another without causing any permanent displacement of the medium itself.
Waves are classified into two
(i) Mechanical Wave:These are waves that require a material medium for their propagation. E.g water wave, wave generated in a spring, and sound wave.
(ii) Electromagnetic wave: These are waves that do not require a material medium for their propagation. E.g light rays, radio wave, x-rays and gamma rays.
Thus from the above explanation, electromagnetic waves do not need a medium to travel through.
