Solution

  1. An electromagnetic wave is a combination of electric and magnetic oscillations.
  2. These oscillations do not require particles to be present in the medium to propagate.
  3. Light is an example of electromagnetic wave, we can see that light travels from sun to earth in outer space without any medium as it does not require a medium to travel

Hence, electromagnetic radiations do not require a medium to travel.
