Detailed explanation-1: -Radiation is the transfer of heat energy in form of radiant energy or motion from one body to another. No medium is required. It takes place through electromagnetic waves.

Detailed explanation-2: -Radiation heat transfer occurs via electromagnetic waves. Unlike conduction and convection, radiation does not need a medium for transmission.

Detailed explanation-3: -Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

Detailed explanation-4: -Electromagnetic waves do not require a medium for travel since they are not transmitted by the vibration of particles. The waves are generated by the oscillation of electric and magnetic fields which can exist anywhere. Thus the waves can exist in solids, liquids, gases or free space.
