No, they don't.
If they did, then light couldn't pass through a vacuum. It would be very dark
here, because the light from the sun, moon and stars could not reach Earth
through the vacuum of space.
No electromagnetic wave, including visible light, requires a medium in order to propagate from
one place to another.
(Notice how we're able to see the sun and the stars by means of the visible light waves that
they emit, which travels across millions of miles of empty space in which there is no 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.
No. Not just light waves but all forms of Electro Magnetic Radiation (EMR) are able to travel through vacuums. e.g gamma rays, radio waves, x-rays, etc.
False, you can see the visible light from stars that travels through the vacuum of space
Any eletromagnetic wave. Light, visible or non visible.
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)
Yes, but only electromagnetic waves, such as visible light or radio waves. Mechanical waves like sound require a medium to travel.
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

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.

Electromagnetic waves (like light) don't require a medium for propagation, unlike mechanic waves (like sound).
Light waves, unlike sound, do not require a medium.
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.

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.
Two waves that do not require a medium to travel would be light waves and gravitational waves. - Zach Harris, B.S. Physics
