Here is major reason that EM radiation needs to travel without medium: between the Earth and the Sun is considered a vacuum, therefore if EM radiation needed a medium to propagate then we would not receive the light from the sun, thereby ceasing alot of vital processes that occur on Earth as a result of interaction with light.
They do not need a medium.
Sound waves cannot travel without a medium. Therefore, any big explosions in space cannot be heard. Light waves can travel without a medium.
because electromagnetic waves transmit energy without compressing the particles of the medium
No. Sound waves must travel through a medium, such as air, liquid, or a solid.
Mechanical waves need a medium to travel in
They do not need a 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 .

Light waves do not need a medium to propagate. Sound waves cannot travel without a medium. Light waves always travel at the speed of light that is 3*108m/s.
Light waves cannot travel through an opaque object.Sound waves intensity is reduced drastically when it crosses an opaque object.Sound waves cannot propagate without a medium whereas light can travel without a medium of propagation.
