Radiation does not require a medium because it travels in the form of electromagnetic waves or particles that do not rely on a medium for transmission. This means that radiation can propagate through empty space, unlike sound waves, which require a medium like air or water to travel through.
Conduction and convection require a medium (such as a solid or fluid) to transfer heat, while radiation does not need a medium and can transfer heat through electromagnetic waves.
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.
No, radiation waves do not require a medium to travel because they consist of particles or waves that can move through vacuum or empty space. This is in contrast to mechanical waves, such as sound waves, which do require a medium to propagate.
Radiation is the method of transferring heat that does not require particles. Radiation can occur through empty space because it consists of electromagnetic waves, such as light and infrared radiation, that can travel without the need for a medium.
Radiation is the heat transfer method that does not require a medium. It can occur through empty space, such as from the sun to the Earth, without the need for a material medium.
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.
Electromagnetic Radiation requires no medium. Light is a form of electromagnetic radiation, and it can traverse the stars.
Light is electromagnetic radiation. It does not need a medium to support it.
Conduction and convection require a medium (such as a solid or fluid) to transfer heat, while radiation does not need a medium and can transfer heat through electromagnetic waves.
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

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.
Conduction and convection require a medium to transfer heat, but space is a vacuum so there is no medium for these processes to occur. Radiation, on the other hand, can occur in the vacuum of space because it does not need a medium to transfer heat energy.
One mechanism where heat transfer doesn't require a medium is radiation. In this process, heat is transferred through electromagnetic waves, such as infrared radiation, without the need for a physical medium like air or water. This allows heat to travel through a vacuum, like in space.
