no they do not, they can travel through vacuums and do not need particles to travel as sound waves do. radio waves are transverse waves whereas sound waves are not
radio waves do not need a medium to travel through.
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.
Mechanical waves need a medium to travel in
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.
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.
they are electro magnetic waves. this means they do not need a medium to travel through
Some waves called mechanical waves e.g sound need a medium to travel through while electromagnetic waves need no medium to travel through e.g light
a wave. Electromagnetic waves (such as light or radio waves) do not need a medium to travel through. Mechanical waves (such as sound waves) require a medium (matter) to travel through.
No, they are Electromagnetic waves and can travel through a vacuum. They do not need a medium.
It is electromagnetic radiation that needs no medium to travel in. Gamma rays, light and radio waves, all forms of electromagnetic radiation, can travel through the vacuum of space very well. In fact, they prefer it.
Electromagnetic waves such as light and radio waves may travel through free space. That is how we get the warmth and light from our Sun. Pressure waves need a distinct medium in which to travel - in which to generate their pressure. Sound waves would be an example, whough weather patterns also need a medium. Vibration waves such as sound may also travel through a solid.
Yes, mechanical waves do need a medium in order to travel. Other waves, such as light, do not (thus they can travel through space).
Waves need not require medium to travel through. Only Mechanical waves like sound waves require medium to travel through. Electromagnetic waves travel in vaccum like light waves. Some waves transmitted in a medium due to disturbances in the medium .
Radio waves can carry sound signals. But by definition radio waves are not sound waves. Radio waves can travel in a vacuum, but sound waves need a physical medium.To explain the apparent contradiction, the sound wave is converted to an electrical signal version that is then used to modulate the radio signal.No it is not
They do not need a medium.
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.
Yes.Yes, sound waves do require a medium to travel through.Yes.They are pressure waves - and they need something (medium) to compress and rarefy.Yes. Sound waves are compression waves. If there's no medium, there's nothing there to compress!
Mechanical waves.For example, sound waves, ocean waves, etc.Many waves need a medium to travel: sound waves, water waves, and seismic waves.Electromagnetic waves do not need a medium.
Electromagnetic waves, as well as gravitational waves.
sound waves are mechanical waves that needs a medium such as air to travel through while radio waves are electromagnetic waves which doesn't need such medium to propagates. ofcourse there is air on the moon so may be the right answer is because astrounates cannot breath on the moon that's why they are using radio waves.
Sound waves need a medium to propagate. Light-waves and other electromagnetic wave (radio, xray) do not.
Sound waves need a medium in order to propogate. Light waves can travel without a medium. The speed of light is 3*108m/s.
Electromagnetic waves do not need a medium in which to travel. They move "best" through a perfect vacuum.
any wave of energy except for electromagnetic waves need a medium to travel through.
Electromagnetic waves don't need anything to travel. This kind of waves does not need a medium to move through, therefore they can even travel through outer space.
