No, only mechanical waves (transverse or longitudinal) require a medium.
I learned this a few weeks ago in Physics 20
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.
This is called absorption. The beam of radiation is absorbed by the medium, leading to the loss of energy and failure to exit the medium.
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.
Conduction and convection require a medium (such as a solid or fluid) to transfer heat, whereas radiation can transfer heat through empty space without a medium. Radiation uses electromagnetic waves to transfer heat instead of relying on a material medium.
Yes, space is a medium through which light and other forms of electromagnetic radiation can travel.
Electromagnetic Radiation requires no medium. Light is a form of electromagnetic radiation, and it can traverse the stars.

-- Long-wave radiation -- Medium-wave radiation -- Short-wave radiation
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.
No, heat radiation does not require a medium to travel. It can travel through a vacuum since it consists of electromagnetic waves. This is why the Sun's heat reaches us on Earth through the vacuum of space.
Yes, space is a medium through which light and other forms of electromagnetic radiation can travel.

Yes radiation.
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.
