Light waves can travel through empty space. You might say that the empty space is the medium in this case.

What are three mediums that waves can travel through?

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.

Why do waves travel through mediums?

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 .

What type of mediums are ocean waves?

Ocean waves are NOT mediums of any sort.

How are light and sound waves different in terms of speed type of wave and mediums?

Light waves travel at approx 300,000 kilometres per second, sound at approx 0.343 kilometres/second.Light waves can travel in vacuum or through some media (there is no such word as mediums!). Sound waves cannot travel through vacuum: they needs a physical medium.

Can Seismic waves travel through space?

NO! Seismic waves can't travel through space. They are mechanical waves. Mechanical waves require going through mediums and there isn't a medium in space.

Why does there have to be a medium for waves to travel through?

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)

How can light waves move through space?

Light waves, unlike sound, do not require a medium.

Differences between light and sound waves?

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

What is true about light waves?

They do not require a medium.

What are two types of waves that describe light?

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

What waves require a medium and what waves do not?

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

Why light waves doesn't require a medium for its propogation but sound waves require?

sound waves move along with the particles of matter through which it passes

What type of waves require a medium?

All types require a medium. Light waves require the free space medium, z= h/Q2 .

What is an example of a wave that doesn't require a medium?

Electromagnetic waves, including light waves.

What do you call waves that bend when changing mediums?

Waves are said to have been refracted when they bend upon changing mediums. The waves have undergone refraction when moving from one medium to another.

How are light waves and sound waves the same?

No. Light waves are electromagnetic waves, and they do not require any medium to exist. Whereas sound waves are compression waves in a material. If there is no material, like in space, then there is no sound.

Did waves carries energy?

most kinds of waves need something to travel through. Water waves, for example, travel along the surface of the water. A wave can even travel along a rope. Gases (such as air), liquids (such as water), and solids (such as rope) , all act as mediums. Waves that require a medium through which travel are called mechanical waves.Some waves do not require a medium to travel through. Light can travel and carry energy through empty space. Waves that can travel without a medium are called electromagnetic waves. :)

Do light waves require a medium?

They dont need it, but they can use it

What types of waves do not require a medium?

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

What are mediums that waves can travel through?

This depends a lot on the type of waves you're talking about. Sound waves, for example, can travel through water, solid, and air mediums, but not through a vacuum. Electromagnetic waves, however, can travel in a vacuum.

What two waves do not require a medium?

The two waves which do not require a medium are electromagnetic waves, also known as light and gravitational waves. Gravity waves have not been detected yet but are predicted by general relativity so are expected to exist.

What waves do not require matter to transfer energy?

Electromagnetic Waves do not require a medium, or matter to move through, to transfer waves. This includes radiowaves, microwaves, infared waves, visible light waves, Ultraviolet waves, X-rays, and gamma rays.

How do you know that light is an example of electromagnetic waves rather than mechanical?

Light does not travel as a mechanical vibration. It can pass through some mediums, but through a vacuum as well.

Is a medium necessary for a wave to travel?

No not really. Sound waves are mechanical waves. They require a medium for propagation. On the other hand, Light waves are electromagnetic and do not require a medium. Hence you cannot hear in space. AND light waves reach the earth from the sun through space- which is a vacuum!!

What happens when you introduce sound waves to light waves?

Nothing. Sound waves are mechanical waves and light waves are electromagnetic waves. The two do not affect each other. Note that electromagnetic waves do not require a medium through which to travel. Sound waves (or any other mechanical waves) require a medium for transmission. And the medium through which a mechanical wave travels will affect an electromagnetic wave.
