It's pure energy.
The term wave is left over from the time that it was thought that a medium might exist (the eather). i.e. before Einstein and photons.

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 is the one kind of wave that does not require a medium?
There are many : radio waves etc
Which kind of wave requires a medium for propagation?
A Sound wave, water wave, earth quake wave. Electromagnetic waves (radio, light, etc.) do not require a medium for propagation.
What is a characteristics of a mechanical wave?
They need a medium to propagate through.
Is a gamma ray an example of a mechanical wave?
No. A gamma ray is a very high frequency electromagnetic wave. Electromagnetic waves propagate as a combination of changing electric field and changing magnetic field. Electromagnetic waves can travel through empty space without any medium. Mechanical waves (such as sound and water waves) propagate by the oscillating particles of the medium - they require a medium to move through.
Do sound require a medium?
Sound waves need a medium to propagate. Light-waves and other electromagnetic wave (radio, xray) do not.

Name one kind of wave that does not require a medium?
An electromagnetic wave (this includes light) does not require a physical medium - it can travel through empty space.An electromagnetic wave (this includes light) does not require a physical medium - it can travel through empty space.An electromagnetic wave (this includes light) does not require a physical medium - it can travel through empty space.An electromagnetic wave (this includes light) does not require a physical medium - it can travel through empty space.
Can a wave travels without medium?
1) Electromagnetic waves2) Gravitational waves Actually, both of these use empty space as a medium - but the point is that they require no additional material, as when a sound wave requires atoms to propagate.
Medium for the wave?
The medium of any wave is the material that the wave energy travels through; in this case water.
What is a characteristics of a mechanical wave?

What medium is disturbed when a light wave is emitted from a flashlight or a candle?
None. Electromagnetic wave do not need a medium to propagate through.
