Radiation needs no medium to travel as it is a simple transmission of electromagnetic waves and here heat is transferred not by heating the particles alternatively as in conduction or convection but directly through waves.

Which heat transfer doesnt need a medium to move through?
Convection.
How is heat transfered by radiation different from conduction and convection?
Radiation does not need any material medium to transfer energy where as the other two conduction and convection need a material medium to perform.
What is the method of heat transfer does not require a medium?
That refers to radiation.
Which is the transfer of energy as waves moving through space?
Radiation
What is radiation in heat transfer?
Radiation in heat transfer is one of three known modes of heat transfer: conduction (as heat transfer in solids and less effective in liquids)), Convection (as in liquids and gases), and radiation (that not necessarily require a medium for the transfer). Heat of sun is transferred to us in the vacuum space by radiation heat transfer.
Which heat transfer doesnt need a medium to move through?
Convection.
What transfer energy through empty space is called?
Transferring energy through empty space is called radiation. There are three types of energy transfer: conduction, convection, and radiation. Radiation is the only energy transfer that does not require a medium. Radiation is a wave of pure energy; one example of radiation is the sunlight that reaches Earth, which is electromagnetic radiation.
What type of wave can transfer energy without medium?
the wave which does not travel through a medium is called electromagnetic wave.

What are the three methods of energy transfer?
radiation convection conduction

Radiation
What is heat transfer by radiation?
All objects transfer thermal energy by infra-red radiation. The hotter an object is, the more infra-red radiation it gives off. No particles are involved in radiation, unlike conduction and convection. This means that thermal energy transfer by radiation can even work in space, but conduction and convection cannot. One good example is the sun. Even though it is millions of kilometers away in space, we can still feel its heat. The thermal energy is transferred by electromagnetic waves.
What exactly is radiant energy?
the process by which heat is transfer from one body to another {in air} while using no medium is known as radiation or radiant energy.
What is the fastest heat transfer?
It depends on the medium of heat transfer. For solids, it is conduction heat transfer. For liquids and gases, it is convection heat transfer. for vacuum (no medium), it is radiation heat transfer.
Can heat be transferred only through solids?
No, energy will transfer between any adjacent bodies, moreover, a medium is not necessary for energy to transfer between objects at all. That would be a little thing called radiation.
Which process transfers thermal energy by contact?
This proess is called conduction. The other processes are convection and radiation. Convection is the transfer of energy through movement, such as boiling water. Radiation is the transfer of thermal energy through a medium or space, such as the sun heating the earth.
