Both electrostatic fields and magnetic fields can influence objects in a vacuum, so EM waves (the combination of varying electromagnetic and electrostatic fields) have influence through a vacuum, that is, in the absence of a physical medium.

Waves that do not require a medium are?
Electromagnetic waves do not require medium for propagation.
All waves need a medium to travel?
No, only surface and mechanical waves need a medium, compressional waves can travel through space. (Such as light from the Sun).I think light (EM) waves are the only ones that can travel through a vacuum. Sound waves require a medium.
Why does there have to be a medium for waves to travel through?
There does not have to be a medium. Light does not require a medium. Mechanical waves require a mediumAnswer 2:Not all waves require a medium for their transmission. Mechanical waves require a medium for their transmission because it is the molecules of the medium which cause the wave to propagate. However, electromagnetic waves do NOT require a medium. (for example light)
What waves require a medium and what waves do not?
Mechanical waves require a medium (substance) to travel in, other waves do not. For example, sound is a mechanical wave and require a medium (air, water, etc.), light is not a mechanical wave and does not require a medium
Do electromagnetic waves need a medium to transfer energy?
NoAnother PerspectiveAll waves require a medium. The medium is what restricts the waves propagation speed. If there were no medium, there would be no limit to the speed with which a wave could travel. The medium of radio waves, or electromagnetic (EM) waves, is space. There have to be more properties of space than I can imagine, but in relation to EM waves, I can think of at least two; elasticity and density. The elasticity of space must be excessive in order to allow waves of extremely short length to propagate with equal fidelity as waves with extremely long lengths. The density of space must be excessive as well, in order for EM waves to be able to travel the distances they do with any representation of the original source.
How em waves different from mechanical waves?
Mechanical waves require a medium while Electromagnetic waves does not.

How are em waves different from mechanical waves?
mechanical waves need a medium to travel through, electromagnetic waves do not. Electromagnetic waves can travel through space, mechanical waves can not.:PElectromagnetic waves do not require a medium, but mechanical waves do.
Waves require a medium in order for energy to be transferred. waves can either travel through a medium or through empty space?
E.M. waves require no medium. Sound waves require a medium.
Why is em radiation the only energy that can travel through space?
Because they are waves that do not require a medium through which to propagate. Space is a vacuum with no medium. For instance, sound waves need air through which to travel.
What distinguishes waves from mechanical waves?
Mechanical waves require a medium for their propagation whereas electromagnetic waves require a medium for their propagation.
