No. Light can travel in a vacuum.That's why we can receive light from sun even though there exists a vacuum in between Earth and sun.

it is sound that requires a medium to travel .. light is an electromagnetic wave ..it doesn't require a medium..


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)


No - unless you call empty space the "medium".


No light of any spectrum doesn't require any medium to travel through. Although it was once thought by scientists that it might travel trough an invisible ether this was disproved.


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 require a medium (substance) to travel in, other waves do not. For example, sound is a mechanical wave and require a medium (air, water, etc.), light is not a mechanical wave and does not require a medium


Yes ,....... light wave can travel through the air ... the light wave does not require any medium.


electromagnetic. for example, light.


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 .


Electromagnetic waves do not require a medium to travel (light, radio).


Radiation does not require a medium.


Electromagnetic waves do not require a medium to travel. Mechanical waces like sound or ocean waves require a medium to propogate (travel).


We know that a mechanical wave requires a medium through which to travel. The source puts the energy into the medium, and it propagates. A sound wave is a good example of this, and we can contrast it with an electromagnetic wave (like light). Light can travel through a vacuum; it doesn't require a medium for its propagation.


Light waves do not require a medium through which to travel. They will travel (propagate) perfectly well in a vacuum. Otherwise, light would not pass through the vacuum of space. It would be very dark here on earth as the light from the sun, moon and stars could not reach Earth through the vacuum of space.


electromagnetic waves generally don't require a medium to travel. the most commonly visible example is "light" which may be either sun's light, light from a bulb or any other source. they travel as transverse waves.


light waves are the only wave that require no medium to travel through. (hence the reason that light from the sun can reach earth, despite the lack of atmosphere). but they can travel through most things...say, air.


no light does not need a medium to travel through


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.


No, light doesn't need a physical medium, like air, to travel. As a matter of fact, light travels the fastest it possibly can, 2.98 * 10^8 meters per second, in a vacuum, like space. If light couldn't travel without a medium, then Earth wouldn't receive any light from the Sun.


Sound waves must travel through a medium, light does not require a medium. Sound waves are longitudinal waves, light are transverse waves.


Light travels at 299,792,458 m/s as both a wave and a particle. Light demonstrates aspects of both. It does not require any sort of medium to travel.


Electromagnetic waves. They travel in space-time. Also, light waves dont require a medium. :) Brittany <3Luv u<3~<3~


Yes. Light waves are electromagnetic waves, which do not require a medium to travel through.Mechanical waves (such as sound) do require a medium to travel through, so sound waves cannot travel through a vacuum.Space is a vacuum. The light from the stars (including our own sun) travel across a great distance in a vacuum to get to us.The accepted speed of light is its speed in a vacuum, which is 299,792,458 m/s.


No. Proof: There's no physical medium between the sun and earth. Light waves are different from sound waves, so light waves are able to travel without matter. That's why sound can't travel in space (a vacuum) but light can travel from the sun to earth through the vacuum of space.
