Sound requires a solid, liquid or gas to carry the vibrations in waves. The air in the atmosphere is actually a collection of gases and so sound travels through what appears to be an empty space.
Sound cannot travel through a vacuum so an explosion two meters away from you in space would be silent (but probably still hurt!)
The difference between sound waves and electromagnetic waves is that they travel through different mediums, in different ways, though some of those can be the same medium. The main difference is that electromagnetic waves can travel through a vacuum. But to be precise, a vacuum is, itself, a medium. It may be devoid of matter, but that does not mean that it is truly empty. It is actually filled with particles called Higg's bosons. Also, the discussion that physicists are having about exactly how electromagnetic waves travel and what kind of medium it is that they travel through is still in debate and may prove to be the most fascinating frontier of 21st Century physics, just like Einstein's Theory of Relativity revolutionized the 20th Century.
No, sound cannot be transmitted without a medium. Sound is a longitudinal wave. NEarly all longitudinal waves cannot travel without medium.
electromagnetic. for example, light.
Electromagnetic waves do not require a medium, so they can transfer through a vacuum, or empty space.
because electromagnetic waves transmit energy without compressing the particles of the medium
Electromagnetic waves do not need a medium in which to travel. They move "best" through a perfect vacuum.
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)
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.
They don't require a medium to travel through. - apex ....what a wanker

The biggest difference is that mechanical waves require a medium to travel through and electromagnetic waves do not.
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.
E.M. waves require no medium. Sound waves require a medium.
Yes! that's how light from the sun gets to the Earth. Electromagnetic do not require a medium to travel through, they can even travel through a complete vacuum.
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.
