No, only mechanical waves (transverse or longitudinal) 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.
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.
Is the correct definition of radiation?
Radiation is process by which heat/energy is transferred from one medium to another without heating the medium for eg, light passing through glass
What is traveling medium of radiation?
Electromagnetic Radiation requires no medium. Light is a form of electromagnetic radiation, and it can traverse the stars.
Does heat radiation require a medium to travel?
Radiation does not require a medium.

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.
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 energy transferred without a medium?
electromagnetic radiation
Is the heat trasferd without medium?
Yes radiation.
Is the correct definition of radiation?
Radiation is process by which heat/energy is transferred from one medium to another without heating the medium for eg, light passing through glass
What do conduction and convection do that radiation does notwhat does radiation use instead?
Conduction and convection badly needs material medium but radiation does not need a material medium as an essential one. It could traverse even in free space in the form of electromagnetic waves
