light waves do not need a medium.

Electromagnetic Waves (EM) do not need a medium. For example visible light, radio waves, microwaves, UV light and x-rays do not. These travel @ 300 million meters/sec in a vacuum.

Do radio waves need a medium to travel through?

No, radio waves do not need a medium to travel through. They are a type of electromagnetic wave that can travel through a vacuum, such as space. They can also travel through other mediums, such as air or water.


When a wave travel through a medium?

Mechanical waves such as sound and vibration require a medium in which to travel. Electromagnetic waves such as radio and light need no transmission medium.


Why don't radio waves need a medium to travel?

Unlike sound waves, which require a medium to travel, radio waves are electromagnetic waves requiring no medium. Visible light is an electromagnetic wave and needs no medium; comprised of photon particles, they travel in a vacuum much like a baseball would, although massless.


All waves need a medium in order to travel?

light waves do not need a medium. Electromagnetic Waves (EM) do not need a medium. For example visible light, radio waves, microwaves, UV light and x-rays do not. These travel @ 300 million meters/sec in a vacuum.


Is it true that all waves need a medium to travel through?

No, not all waves require a medium to travel through. Electromagnetic waves, such as light, radio waves, and X-rays, can travel through a vacuum because they consist of oscillating electric and magnetic fields. These waves do not need a material medium for transmission.


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.


Name a type of wave does not need a medium to travel through?

Electromagnetic waves, such as light and radio waves, can travel through a vacuum because they do not require a medium for propagation.


What waves need a medium and which don't?

Mechanical waves, such as sound waves and ocean waves, require a medium (solid, liquid, or gas) to propagate. Electromagnetic waves, including light waves and radio waves, do not require a medium and can travel through a vacuum.


Do surface waves require a medium?

Yes, surface waves require a medium to travel through. Unlike electromagnetic waves that can travel through a vacuum, surface waves, such as water waves and seismic waves, need a material medium to propagate.


What type of waves can be transmitted in a vacuum?

Electromagnetic waves, such as light waves and radio waves, can be transmitted in a vacuum because they do not require a medium to travel through. These waves propagate through the vacuum of space and can travel long distances without the need for a medium.


What waves need a medium to travel in?

Mechanical waves, such as sound waves, require a medium to travel through. These waves propagate by causing particles in the medium to vibrate and transfer the energy of the wave. Electromagnetic waves, such as light waves, do not require a medium and can travel through a vacuum.


What kind of wave does not need a medium through which to travel?

Electromagnetic waves do not require a medium to travel through. These waves consist of oscillating electric and magnetic fields and can travel through vacuum. Examples include light waves, radio waves, and X-rays.
