Because electromagnetic wave propagation is nothing but the propagation of electric and magnetic energy. Free space has the characteristics such electrical permittivity and magnetic permeability. So in modern terms free space is also considered as a medium but of course a non material medium.
What else can I help you with?
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.
What does a wave require in order to travel?
generally electromagnetic wave does not require any medium while sound waves require a medium (air) for propagation
Is a electromagnetic waves a form of sound?
No, electromagnetic waves are not a form of sound. Electromagnetic waves, such as light, travel through the vacuum of space and do not require a medium to propagate, while sound waves require a medium, such as air or water, to travel.
What types of waves do not require any material medium for their propagation?
Electromagnetic waves, such as light and radio waves, do not require a material medium for their propagation. They can travel through a vacuum because they are created by oscillating electric and magnetic fields. This is in contrast to mechanical waves, like sound waves, which require a medium such as air or water to propagate.
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.
Which type of wave can travel through empty space by electromagnetic waves?
Electromagnetic waves are a type of wave that can travel through empty space. They do not require a medium to propagate because they consist of oscillating electric and magnetic fields that can travel through a vacuum. Examples of electromagnetic waves include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
What type of wave is not a mechanical wave?
Mechanical waves require a medium to travel through. Examples of mechanical waves are sound waves, water waves, a vibrating string. (See related link).Electromagnetic waves (such as light, radio waves, X-rays, microwaves) do not need a medium to travel through, so these are not mechanical waves.Certain phenomena in quantum mechanics exhibit wavelike behavior, and also does not require any medium to travel.An example of a wave that is not a mechanical wave is a light wave. A mechanical wave is a wave that needs a medium to travel through. Light can travel in space, where there is no medium (no air)
Electromagnetic waves can travel through a?
Vacuum
Which wave can travel without a 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.
What are three medium waves can travel through?
Not all waves require mediums to propagate.Sound waves can travel through solid, liquid and gaseous mediums, while, electromagnetic waves do not require any medium to travel through.
What distinguishes electromagnetic waves from mechanical waves?
electromagnetic waves are wave that do not require a material medium for their propagation while mechanical wave requires a material medium for example light wave is an electromagnetic wave it does not require any material medium(depends on air or water)for their propagation i.e even in the absence of air light will still travel... sound wave is a mechanical wave because sound do not travel in a vacuum....
In which mode of transfer of heat does the medium not get heated up?
Infrared radiations. They do not require any medium. So they don't heat any medium. They don't even heat the air through which they pass.
