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.
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.
Light is visible portion of the Electromagnetic spectrum. The velocity of all EM waves is same in a given medium and this means the velocity of all the colors of light travel at the same velocity. After all colour is nothing but an indication of the wavelength. As far as velocity is concerned we will say Light means all colors.
However the velocity of light depends on the property of the medium. In vacuum its velocity is highest about 300,000 KM /sec. In denser medium the velocity stands reduced .
Light will travel in a vacuum. By medium I suppose you mean something such as glass. Some mediums will block light, some will allow it to pass.
no, it travels through space without any medium
No - unless you call empty space the "medium".
no light does not need a medium to travel through
No.
Yes ,....... light wave can travel through the air ... the light wave does not require any medium.
electromagnetic. for example, light.
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.
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, 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.

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.
Light energy.

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 .

Visible light and x-rays are both forms of electromagnetic radiation, and do not require a medium to travel through.
it is sound that requires a medium to travel .. light is an electromagnetic wave ..it doesn't require a medium..
