    Answer: True

    Explanation: Electromagnetic radiation travels in the form of waves, and while it can travel in a medium, electromagnetic waves actually do not need a medium to travel.

    And one of the principles in the physics is that all electromagnetic waves travel at the speed of light, c, in a vacuum, so all electromagnetic waves travel at the same speed in a vacuum (not in materials, different waves can travel at different speeds in some materials), so this is true.
