Wrong.Earthquake S-waves are just one example of transverse waves that do need a medium to travel through. Specifically they need a solid medium and cannot not travel through either liquid or gaseous mediums.Perhaps you are confusing transverse waves in general with electromagnetic waves (which happen to be transverse) but do not need a medium because they are a propagating electric field - magnetic field each creating the other in a cycle.

Because the theory is that this is what the form is. If it were a longitudinal or compressional form (such as sound) it would need to travel through a medium of some sort to compress the particles of that medium. But electromagnetic radiation can travel even in a vacuum.
Mechanical waves need a medium to travel in
there is no need of medium to travel

Yes, but only EM waves don't.

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. :)
It is not so much longitudinal vs. transverse - it is the type of wave. Mechanical waves, by definition, travel through matter. That includes sound waves. Mechanical waves, however, can be both longitudinal and transverse - and both require a medium.

Shear / transverse waves do not travel through liquids.

light waves do not need a medium. Electromagnetic Waves (EM) do not need a medium. For example visible light, radio waves, microwaves, UV light and x-rays do not. These travel @ 300 million meters/sec in a vacuum.
Radiation doesnt need a medium because it travels through space
waves such as transverse waves, like moving a rope up and down causing waves, does require a medium but energy in the form of light (its still debatible weather its a particle or wave) doesnt need a medium,like electromagnetic waves
