Electromagnetic waves can travel with or without a medium.

Heat waves, light waves, electromagnetic waves,

because electromagnetic waves transmit energy without compressing the particles of the medium

No. Waves that require a medium to travel in are called mechanical waves. Electromagnetic waves are not mechanical waves and do not require a medium.

Electromagnetic waves can travel through space without a medium.

Electromagnetic Waves can travel through space without any material medium.

The mechanical waves exist in a medium (water, land, air, metal, etc.). The electromagnetic waves can "travel" through vacuum, that is, without a medium. By laastos.

mechanical waves need a medium to travel through, electromagnetic waves do not. Electromagnetic waves can travel through space, mechanical waves can not.:PElectromagnetic waves do not require a medium, but mechanical waves do.

This is perhaps due to the fact that electromagnetic waves do not require a medium to travel in. They can move through a vacuum without being diminished.

Electromagnetic waves can travel through any medium as they are non- mechanical waves. They can also travel through vacuum.

The only way energy can travel without a medium is by electromagnetic waves, or in other words, photons.

Electromagnetic waves can travel in a vacuum because this wave is a moving magnetic and electric field. These fields do not require a medium to travel in, and they "carry" the energy of the electromagnetic wave with them. This makes the electromagnetic wave different from mechanical waves like sound.With mechanical waves, we find the source putting the energy of the wave into the medium through which it is going to travel. Electromagnetic waves carry the electromagnetic energy away from the source without a need for a medium through which to travel. The moving fields carry the energy of the wave, and a vacuum presents no obstruction to the waves at all.

No. They are two different types of waves. Mechanical waves require a medium, such as air, to travel through. Electromagnetic waves do not need a medium to travel through.

mechanical waves need a medium to travel through and electromagnetic waves don't

Waves cannot travel without a medium. These waves must travel though some sort of medium in order to be heard.

No, they are Electromagnetic waves and can travel through a vacuum. They do not need a medium.

light waves or electromagnetic waves are transverse and sound waves are longitudinalElectromagnetic waves can be both transverse and longitudinal waves. Transverse waves are like ocean waves. They move the medium perpendicular to the medium which is the substance the wave is traveling on. Longitudinal waves are like a slinky. They compress and rarefact (The coils get close and move away). Longitudinal waves move the medium parallel to the energy.Electromagnetic waves don't need a medium to travel. They can travel on the medium but they don't need a medium to travel through.Mechanical waves need a medium to travel. They can't travel without one.That is why in starwars when the deathstar blows up and your whole room shakes when it does isn't possible because in space there isn't any air! Sound is a mechanical wave, since there isn't any medium there can't be any sound. If you yell in space nothing would happen because there isn't a medium for the sound waves to travel on. You can see light in space because light is an example of an electromagnetic wave which doesn't need a medium to travel.Cranberryhead. :)

Electromagnetic waves do not need a medium in which to travel. They move "best" through a perfect vacuum.

Electromagnetic waves can travel through space or a medium while mechanical waves need matter to transfer energy.Apex- They don't require a medium to travel through.

Mechanical waves require a medium to travel, where electromagnetic waves do not.

Electromagnetic waves, as well as gravitational waves.
