Do visible light waves require a medium?
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.
Why are light waves are able to travel through vacuum?
Light "waves" are able to travel through a vacuum because light is only halfway "wavy". Light is actually a collection of particles, known as photons. Photons, because they are particles, are able to travel through a vacuum; unlike waves, they don't need a medium to travel from place to place. If you're interested in what I mean by "halfway wavy" look up the quantum particle-wave duality nature of light on Wikipedia.
What type of wave does not need a medium?
An electromagnetic wave does not need a medium. It is able to pass through a vacumn.
Does light require a medium to travel through?
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.
How do you know that electromagnetic waves can travel thought a vacuum?
Light being electromagnetic wave is able to traverse right from Sun to the Earth through vacuum existing in between the two. This confirms electromagnetic wave can traverse through free space. Now free space itself is a medium but not a material medium.
Would you be able to observe the refraction of light if the incident light were perpendicular to the medium?
No, you wouldn't be able to.
Is it possible for any type of particles to have velocity greater than the velocity of light. Justify your answer?
Short answer: Yes. Long answer: Yes, it is possible for particles to travel through a medium (not a vacuum!) faster than light can travel through that medium (not a vacuum!), which gives rise to Cherenkov radiation. Tachyons - a type of superluminal particle that is theorized but has never been observed - should be able to travel faster than light, but they would not be able to travel at or below light speed.
Does the wave nature of light states that light needs a medium through which to travel in different waves?
Light been found as electromagnetic wave does not need any material medium to get propagated. Even in free space (vacuum) it is able to travel.
Does visible light requrie a medium?
since light wave is electromagnetic wave and is able to travel through vacuum. eg.x-ray gamma ray radio waves etc hence due to the electromagnetic properties of visible light it does not required medium

If the wind blows at the speed of light can light travel through it?
Since you have already postulated the fantasy that the wind is blowing at the speed of light, you might just as well go ahead and decide whether or not you want light to be able to travel through it, then wave the same wand and make it so. There's no evidence that motion of a material medium has any effect on the ability or inability of light to pass through it, so a first pass at this sorcery produces the speculation that the light would have no problem.

Can you break a infrared beam with another infrared beam or another light source?
In general, no. You may be able to exploit non-linear properties of the medium through which light is shining, but you cannot stop light using just other light.
What type of wave does not need a medium?
An electromagnetic wave does not need a medium. It is able to pass through a vacumn.
Can sound travel through a vaccum?
Sound is basically the vibration of atoms or molecules of a solid, liquid, or gas that propgate throughout the medium. Sound MUST have a medium to travel through; if there were no medium there to vibrate in, it would have no frequency and therefore would not be able to be heard. Since a vacuum is a space devoid of all matter, there would be no medium for the sound waves to propgate in, so therefore, no sound.
How is a refractometer used in home brewing?
A refractometer measures the refraction of light through a medium. In beer manufacture it tests for the density of sugars in the beer and is able to tell you the sweetness.
