an electromagnetic wave such as x rays
<u>Explanation:</u>
Electromagnetic waves are the waves it can be observed in the outer space between the planets, the other waves such as the sound waves are the mechanical waves, which need the medium for its propagation.
There is no medium between the planets so there is an empty space for the propagation. Hence the sound waves do not pass through the medium.
The mechanical wave can have the material for the propagation. The electromagnetic waves can be used to transport the energy from one form to another. It does not require the material medium.
