They do not need a medium.
because electromagnetic waves transmit energy without compressing the particles of the medium
electromagnetic radiation, for example light
The only way energy can travel without a medium is by electromagnetic waves, or in other words, photons.
They can both travel through a medium.

Electromagnetic waves.
Electromagnetic waves can travel through space without a medium.

Electromagnetic waves.
Electromagnetic Waves can travel through space without any material medium.
The biggest difference is that mechanical waves require a medium to travel through and electromagnetic waves do not.
Travel through empty space without a physical medium.
Waves need not require medium to travel through. Only Mechanical waves like sound waves require medium to travel through. Electromagnetic waves travel in vaccum like light waves. Some waves transmitted in a medium due to disturbances in the medium .
