What waves can transfer energy with out a medium?
Electromagnetic waves, such as light and radio waves, can transfer energy through a vacuum without the need for a medium. This is because electromagnetic waves are made up of oscillating electric and magnetic fields that can propagate through empty space.
What type of wave does need medium to travel?
Mechanical waves, such as sound waves and water waves, require a medium in order to propagate because the particles of the medium are involved in the transfer of energy from one point to another. In the absence of a medium, these waves cannot travel.
Why does electromagnetic radiation need a medium through which to travel?
No medium is necessary for the propagation of electromagnetic radiation. This radiation is a moving wave that has an electric component and a magnetic component, and it is self sustaining after its creation. The actual energy of the wave is carried in the two moving fields of force, and not in the medium through which it is traveling. The wave travels out from its point of origin through even a vacuum. Any other medium will tend to absorb some of the energy of the wave.

What are waves that need a media?
Mechanical wavesMechanical waves need a medium to move through. An example is sound moving through the air. Sound is a compressional mechanical wave and the medium is the air. That's why there isn't any sound in space.
How is heat transfered by radiation different from conduction and convection?
Radiation transfers heat through electromagnetic waves, such as sunlight or infrared radiation, without requiring a medium. Conduction transfers heat by direct contact between materials, like a metal spoon heating up when placed in a hot drink. Convection transfers heat through the movement of fluids, like air or water, which carry heat from one place to another.
One difference between sound waves and electric radiation?
sound waves require a medium while electric radiation doesn't want any medium. It can be even transmitted through vaccum.

What can electromagnetic waves transfer waves without?
Electromagnetic waves can carry energy from place to place without a medium. Further, any frequency of radiation from a mass transfers energy in the form of waves. As to whether it is with or without a medium is yet unknown and yet to be experimentally proved or disproved.

What is a wave that doesn't require a medium for propagation?
Electromagnetic waves (like light) don't require a medium for propagation, unlike mechanic waves (like sound).
What is the difference between electromagnetic waves and radiation?
No difference at all. Radio waves are one of many types of electromagnetic waves.
What is difference between electromagnetic waves and mechanical waves?
Mechanical Waves:1.Mechanical waves need a material medium for their propagation.2.These waves are produced due to the vibrations of the particles of the medium.3.They have low speed.Electromagnetic Waves:1.Electromagnetic waves do not need any material medium for their propagation.2.They are caused due to change in electric and magnetic fields.3.They have high speed.
How does radiation travel?
Radiation travels through space or material in the form of energy waves or particles. The three main types of radiation are electromagnetic (such as light), particle (such as alpha or beta particles), and acoustic (such as sound waves). The movement of radiation is determined by factors such as its energy level and the medium it is traveling through.
Are electromagnetic waves longitudinal or transverse?
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. :)
