Electromagnetic waves aren't really waves in the same sense that water waves or sound waves are; no medium is necessary. See below for an alternative ... "theory." ---- The electromagnetic wave medium is not understood by physicists. The medium is z, the 'free space impedance" what Maxwell called the Ether. The Ether was dismissed by physicists in the M-M "experiment". The experiment was bad the ether is z=375 ohms.
The ether z=W/Q, where W is the magnetic charge in Webers (volt seconds) and Q is the electric charge in Coulombs. W= 500 e-18 Webers and Q= 4/3 e-18 Coulombs.
z is related to Planck's Action Constant h=2/3e-33 Joule seconds = WQ!
Electromagnetic waves energy E=hf = WQf, the medium exists.

Does a electromagnetic wave need a medium to travel?
Electromagnetic waves do not need a medium in which to travel. They move "best" through a perfect vacuum.
Can electromagnetic waves travel without a medium?
They do not need a medium.
Do all waves need a medium?
No...electromagnetic waves require no medium
Why radiation waves does not need any medium?
they do. As you might be aware of, light( radiation wave) is made of electromagnetic wave and its medium is electromagnetic field. So basically the medium of radiation waves is electromagnetic field.
What type of wave does not need a medium?
An electromagnetic wave does not need a medium. It is able to pass through a vacumn.
Can electromagnetic waves travel without a medium?
They do not need a medium.
Does a electromagnetic wave need a medium to travel?
Electromagnetic waves do not need a medium in which to travel. They move "best" through a perfect vacuum.
Do all waves need a medium?
No...electromagnetic waves require no medium
What do electromagnetic waves not need?
A fluid or medium.
Why radiation waves does not need any medium?

What type of wave does not need a medium?
An electromagnetic wave does not need a medium. It is able to pass through a vacumn.
Why does a wave travel a medium?
Waves do not need a medium all time.it depends like u need no medium when it is electromagnetic wave.
How mechanical and electromagnetic wave are different?
The biggest difference is that mechanical waves require a medium to travel through and electromagnetic waves do not.
What kind of energy does not need medium to travel?
electromagnetic waves
What waves need a medium and which don't?
sound waves, water waves, shockwaves need mediums. Electromagnetic waves do not need a medium
Light is not a wave because it does not need a medium?
That statement assumes that every wave needs a medium, which is a false assumption. An electromagnetic wave, such as light, does not need a medium.
What does Electromagnetic energy does not need?
It needs you to study your courses on FLVS.
