Does heat radiation require a medium to travel?
Radiation does not require a medium.
What is the method of heat transfer does not require a medium?
That refers to radiation.
Why radiation waves does not need any medium?
they do. As you might be aware of, light( radiation wave) is made of electromagnetic wave and its medium is electromagnetic field. So basically the medium of radiation waves is electromagnetic field.
In which form of heat transfer is a medium not required?
Heat transfer by means of radiation doesn't heat the medium. In fact, radiation doesn't even require a medium in order to work. Strictly speaking, convection doesn't heat the medium either. Convection transfers heat by moving the medium around. Of course, heat also spreads throughout the medium by conduction while the convection is going on.
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 the three types electromagnetic spectrums?
-- Long-wave radiation -- Medium-wave radiation -- Short-wave radiation
Does a radiation wave need a medium to travel?
No. Heat from the sun gets to the earth by radiation, and there is no medium inbetween the sun and the earth because space is a vacuum.
Through what medium does light travel?
Light travels through a vacuum, and through the densest metals (though not usually very far). But then gamma radiation and radio waves are examples of light...
Why can heat travel through space by radiation but not by conduction and convection?
For conduction and convection we need a material medium. But for radiation such a meaterial medium is not necessary. So in free space radiation can pass through easily.
What is the medium of speed traveling through air?
Air is the medium (if you are talking about something travelling through it).
How does the speed of a wave relate to the density of the medium it is traveling through?
The faster the wave, the denser the medium
What is energy transferred without a medium?
electromagnetic radiation
